Question

Why do you find it hard to push a glass tumbler down into water

Answer 1

when the tumbler is pushed down into water vertically the air present in the tumbler exerts pressure on the water and so we find hard too push it down.

Answer 2

Answer:

It is difficult to push a tumbler upside down into water because it is filled with air. The air does not allow water to come inside.In order to push the tumbler inside we have to apply a greater force than water. If we will tilt the tumbler the air will go out and the water will come inside the tumbler.
