Question

With neat diagrams describe an experiment to show that pressure increase if the surface area is decreased keeping the applied force the same

Answer 1

Answer:

A LIQUID EXERTS PRESSURE AT THE BOTTOM OF ITS CONTAINER :

take a balloon and tie it at the lower end of a glass tube and hold vertically as in fig (a) pour some water in the tube , balloon bulges our as in

(b) Because water column exerts pressure (∴ liquid has weight at its bottom . force on balloon is equal to the weight of Thrust water column which is called the thrust P = Thrust / Area

This shows that a liquid exerts pressure at the bottom of the container in which it is kept.
