Question

When a force of 5 N acts on a surface,it produces a pressure of 500 Pa.The area of surface then must be :
(a) $10c{m}^2$ (b) $50c{m}^2$ (c) $100c{m}^2$ (d) $0.01c{m}^2$

Answer 1

Pressure = $\frac{Force}{Area}$

Area = $\frac{Force}{Pressure}$
= $\frac{5N}{500Pa}$
= 0.01 $m^2$
= 0.01 $\times {10}^{4}c{m}^2$
= 100$c{m}^2$

(c) is the correct option.
