Show that liquid in equilibrium of rest exerts normal force on the surface in contact with it.

The "______" exerted by a liquid at rest per unit area normal to the surface in contact with the liquid is called pressure.

Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface. Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

A spherical ball of mass m =5kg rests between two planes which make angles of 30^(@) and 45^(@) respectively with the horizontal. The system is in equilibrium. Find the normal forces exerted on the ball by each of the planes. The planes are smooth.

What is fluid? Show that fluid exerts pressure and prove that the force acting on a fluid in equilibrium of rest have to be perdicular to its surface.

On the surface of the liquid in equilibrium , molecules of the liquid possess

Thrust of a liquid always acts ____ to the surface of contact.

A force acting normal to a surface is called________
