Question

If you cover a hole of vessel filled with water, you will feel pressure. True or False? Justify your answer.

Answer 1

The liquid at the bottom of the container (in which it is filled) exerts some pressure which depends upon the height of water filled in the container. The value of pressure exerted by the liquid at the side walls of the container; at any point depends upon the amount of water above that point. Since in a container the height of liquid above a surface is same for all the points, therefore, liquid exerts same pressure at a particular level.

So if there is water above the level of the hole, then we will feel pressure.

So it is true.
