This started to bother me today. In the first picture, there's a cup wheres a certain amount of water in it. A ball made of aluminium hasnt been dropped in the cup yet.

In the second picture, the ball has been dropped in.

The ball has not sinked, a string is holding it.

Now please tell me, how did the pressure on the botton of the cup created BY THE WATER change?

I mean, the water level just rose. So the pressure should also.

But there seems to be another solution to the problem, and I just cant figure it out.

The equation for liquid pressure is p= RO*g*h.

Thanks in advance,
