about water polo being submerged in water?

Question

when a water polo ball is submerged below the surfaces in a swimming pool and released from rest, it is observed to pop out of the water.how would you expect the height to which it rises above the water to vary with depth of submission below the surface?would you expect the same result for a beach ball?for a table tennis ball?

Answer 1

The bigger the ball the higher it pops. The further down you push it the higher it pops up. The suction that is created below it as it begins to rise forces it up... the bigger the ball the more pressure pushing it up.
