Question

(A)Define hydrostatic pressure

Answer 1

The pressure exerted by a fluid (gas or liquid) at equilibrium due to the force of gravity is called hydrostatic pressure. The hydrostatic pressure existing in roots which push the water up in xylem vessels. Hydrostatic pressure increases with depth because of the increasing weight of fluid exerting downward force from above. This change in hydrostatic pressure with depth is known as hydrostatic pressure 

Answer 2

It is the pressure that is exerted by a fluid at equilibrium at a given point within the fluid , due to force of gravity. It increases the proportional of depth measured from the surface because of the increasing weight of fluid exerting downward force from above. Hope you will understand :-) :-) :-) :-) :-) :-).
