It will tip to the right because the buoyant force on the left is neutralized by the string but the buoyant force on the right "Pushes" only against gravity,

Left has more weight pushing it down, string, ball, plastic, and water.
Right has the same water, but the string and the ball don't add any weight to the scale because they're suspended elsewhere

The force balance is as follows. Both balls are same volume it looks and displace the same amount of water, therefore the weight of water is the same on both. On the right side, the gravitational force is on the ball is higher than the boyant force exerted by the water on the ball, so the ball is trying to fall downwards. This force is concentrated on the string which is attached to an external structure and has no effect on the platform. On the left side, the boyant force that the water exerts on the ball is greater than the gravitational force of the ball, and this created a new upward force with results in tension in the string and pulls up on the left platform. Therefore the total downward force on the right platform js larger than the left and the scale tips to the right

Left. Same volume is displaced on each side which means the same amount of water in each beaker, but one beaker has the added weight of a ping pong ball in it.

to get the correct answer, imagine if the common factor, the glass of water, were removed entirely. if the scale tips one way without the glass of water, it must continue tipping that way once the glass of water is introduced on both sides

if we assume mass of water and the glass is the same it's only ping pong ball with string vs nothing, so left side goes down

the ping pong ball floats because it is less dense than water, but it's mass is applied downwards to the scale

Weight on the left:
Weight of the water + weight of the ping pong ball

Weight on the right:
Weight of the water + Buoyant weight of the steel ball = Weight of water + weight of displaced water

Since density of water > density of ping pong ball, scale tips to the right.

The right side has more mass in it (sort of) so it will tip to the right. The right is the same thing as saying take the steel ball out and replace it by water. The additional mass of the theel ball is held by the string, the other part is the weight of the replacement water.

The right side has more mass in it (sort of) so it will tip to the right. The right side is the same as saying that the steel ball was replaced by water. The weight that the string is holding is the weight of the steel ball minus the weight of the replacement water, so the weight of the replacement water (steel ball's volume's worth of water) gets added to the right side.

I couldn't believe that, why would displacing water add weight if the object displacing it is hold up?
So I took a cup of water, put it on kitchen scale, hold a spoon inside it without touching the cup the scale shows increase in weight.
I guess I learned something

The joke is in the fact that the string doesn't need to suspend the entire weight of the steel ball. Whenever you submerge anything in water, it becomes lighter. This is why submarines don't just sink into the bottom of the ocean. Sine the steel ball has become lighter, some of the weight of the steel ball must have gone somewhere. Where has it gone? To the right side beaker, adding more weight to the right side.

The water still exerts buoyant force on the steel ball and suffers from the reaction force of it, It's only the gravitational part that is removed by the string. So, yeah basically what you're doing is essentially pushing the water down or another more comfortable way of seeing is that since you need to exert less force to hold the spoon up, the water is shouldering some of the weight for you.

I like to think of it as the same thing as if you were forcefully pushing the ping pong ball down against the boyancy force of whatever you call it. Obviously you would be generating more force to the scale if you did that. And the steel ball is achieving basically the same effect by its own weight.

Think from the perspective of the bottom plate.
For it, the forces acting on it are :
Weight of the water + Gravitational weight of the ping pong ball - Buoyant weight of the ball (action) + Buoyant Weight of the ball (reaction)

If all the sizes are equal, then it depends on the material of the string and the material of the liquid.

but on a better consideration, the material of the ping pong ball is heavier than nothing, and it adds up to the weight of the glass at the left, thus that glass is heavier (also the string on the right doesn't push anything)

I'll try to give a more convincing argument. Know that we assume that by density: Steel > Water > Ping Pong ball

Here, the combined weight of the left beaker is Water + Ping Pong ball and on the right is Water + Steel ball.

On the left, the weight of the entire system has to be borne by the plate because there's nothing else to share it.

On the right, the top string will manage all the excess weight that the water can't (experienced first hand by >>16590432) and thus will reduce (weight of the steel ball - weight of water ball) from the system, which means that the total sum on the right is (Weight of water + weight of water ball), which is heavier than the left.

As long as the ball on the right is heavier than water, doesn't matter if it's steel or mercury, and the ball on the left is lighter than water, doesn't matter if it's some polymer or lithium, the result will be the same, it's a comparision between the weight of water and weight of the left ball's material, not a comparision between steel ball and ping pong ball.

Anonymous at Tue, 18 Feb 2025 18:25:13 UTC No. 16590507

Now the situation is identical, the water doesn't know whether there is an orb of a ping pong ball or steel ball in it. So we know that the scale is balanced, it doesn't tip to either direction.

We also know that in this balanced state the left supporter is pushing the ping pong ball down. If we remove this the scale will tip to right because the balancing support was taken from the left.

Anonymous at Tue, 18 Feb 2025 19:23:10 UTC No. 16590560

>>16590501
The system on the right is lighter also because the string also holds the water on the top of the steel ball. I sugest that could be the most significant element of what makes the answer to this question counter-intuitive.

Anonymous at Tue, 18 Feb 2025 20:03:31 UTC No. 16590608

When you have an object in water, the system weighs exactly the amount of water there is plus the weight of the displaced water. The only difference now is that the ping pong ball is lifting the left side up by the string. So scale is tipping to the right.

No. It will tip to the left. The force pushing down into the water is being redirected to hold up the water at a higher level. Removing the support will lower that water, raise the ping pong ball, and then the left side will have to support the water AND the ping pong ball.

If your nonsense regarding anything in the water heavier than water pushing the scale down were applied then removing the cable from the right would make the scale tip to the left.

do you know how lack of water will affect force on the string on the right? Hint: now about 1/8th of steel ball is supported by buyoyancy (if you ever tried to pick up heavy boulder from underwater you'd know how it works) if you cut string on the left pingpong ball will go to the surface (most of it above even) and level of water will drop. Unless this pingpong ball is actually heavier than water and that's not a string then left is heavier untill right string gets cut, and then maybe pingpong ball is actually made of tungsten then left wil be going down.

First everything is balanced. Then we remove the downward pushing force from the left side, that will cause tipping to the right (obviously). The ping pong ball support is switched to the original support from the bottom in which case there's no outside forces acting on the left beaker. So it still tips to the right, or even if the ping pong ball was floating it would still tip to the right.

That "downward force" from the ping pong ball is completely negated by the upward force on the water from the displacement. Effectively the fluid nature of the water redirects the force counteracting buoyancy. Think of it like a pulley. Removing the support for the ping pong ball changes the weight on the scale from the weight of the water+force opposing buoyancy-the weight of the water supported by the ping pong ball to the weight of the water+the weight of the ping pong ball. That's an increase.
