Question

12.The pressure of a gas contained in a cylinder with a movable piston is 300 Pa. The area of the piston is 0.5 m2. Calculate the force that is exerted on the piston. *

150 N

200 N

600 N

250 N

​

Answer 1

Given:

• Pressure(P) = 300pa

• Area(A) = 0.5m^2

To find:

• The force(F)

Solution:

We know that,

P = F/A

∴ F = P ×A

On putting values in the formula, we get,

=> F = 300 × 0.5

=> F = 150N.

Hence, the force that is exerted on the piston is 150N.
