When a pressure measuring device is immersed in a liquid, a restoring force of 2 N is exerted by the spring. If the area of cross-section of the pistion is 10 `cm^(2)`, what pressure does the fluid exert on the piston?

A cylinderical vessel contaning liquid is closed by a smooth piston of mass m. the area of cross-section of the piston is A. if the atmospheric pressure is P_(0), Find the pressure of the liquid just below the piston.

Calculate the pressure when a force of 200 N is exerted on an area of 5 m^(2)

A force of 40 N is applied on a nail , whose tip has an area of cross-section of 0.001 "cm"^(2). Calculate the pressure on the tip.

Calculate the pressure when a force of 200 N is exerted on an area of 10 m^(2)

A force of 500 N acts on the bullet of area of cross -section 0.5cm^(2) . What is the pressure on bullet in S.I. system?

A cylidrical vesel containing a liquid is closed by a smooth piston of mass m as shown in the figure. The area of cross section of the piston is A. If the atmospheric pressure is P_0 , find the pressure of the liquid just below the piston. ,
