Question

If a perpendicular force F is applied to a certain area A and produces a pressure P, what is the new pressure on the surface when the same force is applied to an area 2A?

a) P/2
b) P
c) 2P
d) 4P

Answer 1

When force F is applied to doubled area 2A, the new pressure would be P/2 because pressure is inversely proportional to the area over which the force is applied.

Step-by-step explanation:

The question revolves around the concept of pressure in physics, which is defined as the force per unit area applied perpendicularly to a surface. The formula to calculate pressure is P = F/A, where P is the pressure, F is the force, and A is the area. So, when the same force, F, is applied to an area that is doubled (2A), the new pressure is half of the original pressure because pressure is inversely proportional to area when force is constant. Therefore, the correct answer is a) P/2.
