What is the amount of force required to produce 150Pa pressure on 20m2 area? If the area became doubled by keeping force constant, then
what will be the change in pressure?
Answers
Answer: The force required is 3000N.
When the area is doubled the pressure is 75 Pa.
Explanation: The Numerical=
1) Let the force required be N.
Therefore => 150 Pa = N/20m^2
=> 150 Pa x 20m^2 = N
=> 3000 = N
2) Since the area is doubled,
Therefore => 20m^2 x 2
=> 40m^2
Therefore=> Pa = 3000N/40m^2
=> Pa = 75N/m^2
= 75 Pa
