Question

normal force of 500 Newton can produce the pressure of 250000 pa. calculate the area in centimetre square on which the force shall at the exart the
pressure​

Answer 1

Answer

• Area , A = 2 × 10⁻⁷ cm²

Given

• Normal force of 500 Newton can produce the pressure of 250000 pa

To Find

• Area in cm²

Solution

Force , F = 500 N

Pressure , P = 250000 P

Area , A = ? cm²

We know that , " Pressure is defined as Force acting per unit area "

$\implies \tt P=\dfrac{F}{A}\\\\\implies \tt 250000=\dfrac{500}{A}\\\\\implies \tt 2500=\dfrac{5}{A}\\\\\implies \tt A=\dfrac{1}{500}\\\\\implies \tt A=0.002\ m^2\\\\\implies \tt A=0.002 \times (10^{-2}cm)^2\\\\\implies \tt A=2 \times 10^{-3}\times 10^{-4} cm^2\\\\\implies \tt A=2 \times 10^{-7} cm^2$
