Question

A force of $300$N, while actin on an area A, produces a pressure of $1500$ Pa. What is the magnitude of A in $c{m}^2$?

• A. $1000c{m}^2$
• B. $3000c{m}^2$
• C. $4000c{m}^2$
• D. $2000c{m}^2$

Answer 1

The correct option is D $2000c{m}^2$

$Pressure=\frac{force}{area}$
$Therefore,area=\frac{force}{pressure}$
$area=\frac{300N}{1500}Pa=15sq.m$
$Now,1m=100cm.$
$Therefore,100\times \frac{100}{5}=2000sq.cm$
