Question

A pressure of 10 kPa acts on an area of 0.3 $m^2$. The force acting on the area will be :
(a) 3000 N (b) 30 N (c) 3 N (d) 300 N

Answer 1

Answer: (a) 3000 N.

Given,

Pressure = P = 10 kPa

Area = A = 0.3 $m^2$

We know that,

Pressure = $P=\frac{F}{A}$

$\Rightarrow F=PA=10\times {10}^3\times 0.3=3000N$.
