Question

A force of 0.5N is applied to an object of an area 250 cm2

. Calculate the pressure​

Answer 1

Answer:

The pressure on the object calculated is $20Pa$.

Explanation:

Given,

The force applied on an object, F = $0.5N$

The area of the object, A = $250cm^{2}$

Convert $cm^{2}$ in $m^{2}$

• $1cm^{2}$ = $10^{-4}m^{2}$
• $250cm^{2}$ = $250 \times 10^{-4} m^{2}$ = $0.025m^{2}$

The pressure on the object, P =?

Now, as we know,

• Pressure is the force per unit of time

Therefore,

• P = $\frac{F}{A}$
• P = $\frac{0.5}{0.025}$
• P = $20Pa$

Hence, the pressure on the object calculated is $20Pa$.
