If the pressure produced by a force over an area of 100 cm2 is 30 Pa, then calculate the force applied (A) 0.3N
(B) 0.4 N
(C) 0.5 N
(D) 0.6 N

Explanation:

Given:

Pressure = P = 20 Pa

Area = A = 100 cm² = 0.01 m²

Required:

Force = F = ?

Formula:

P = F/A

Solution:

For F it becomes:

=> F = P * A

=> F = 30*0.01

=> F = 0.3 N

that would be b i just took the test : )
