Solution

The correct option is A True

The force applied perpendicular to the surface of an object per unit area over which that force is distributed is known as pressure.
A force acting parallel to a surface does not produce any pressure on the surface
The magnitude of pressure is maximum when the force is perpendicular to the surface.
The magnitude of pressure is minimum when the force is parallel to the surface.
Hence, The given statement “A force acting parallel to a surface does not produce any pressure on the surface.” is True.

Q. Select the correct one from the statements given below:

(i)

At any point in a static fluid, pressure acting on it will be same in all directions.

(i i)

Forces acting on a fluid in equilibrium have to be parallel to the surface.

A force of 2500 N produces a pressure of 50,000 Pa. Calculate the area of the surface on which the force acts.

Q. The force of surface tension acts tangentially to the surface whereas the force due to air pressure acts perpendicularly on the surface. How is then the force due to excess pressure inside a bubble balanced by the force due to the surface tension?

Statement 1: For the same load/force acting on two different surfaces, more pressure is developed on the surface with a smaller area.
Statement 2: Pressure is defined as thrust(force acting normally to the surface) per unit area.
