Question

A stone weight 500N calculate the pressure exerted by it ,if it makes a contact with a surface of area 25 square cm

Answer 1

$\large{\underline{\sf{\red{Find:\rightarrow}}}}$

• $\rm{Pressure??}$

$\large{\underline{\sf{\orange{Given:\rightarrow}}}}$

• Weight of stone = 500N
• Surface of area = $\rm{25cm^2 =0.0025m^2}$

$\large{\underline{\sf{\green{Formula \ used:\rightarrow}}}}$

$\boxed{\bf{P=\dfrac{F}{A}}}$

$\large{\underline{\sf{\pink{SoLution:\rightarrow}}}}$

Putting value in formula we get,

$\bf{\implies P= \dfrac{500}{0.0025}=200000 \ Pa }$

$\bf{\underline{\therefore Pressure = 2\times 10^5 \ Pa \ or N/m^2 }}$

• Pressure is the physical force exerted on an body or object.
• SI unit = $\sf{ 1 N/m^2, 1 kg/(m.s^2)}$

Answer 2

Answer:

hey buddy answer is

stone weight = 500N

surface of a area = 25 square cm

square cm converted into square meter

= 0.0025 square meters

force

pressure = ----------

acceleration

500

= ----------

0.0025

= 20000

5

pressure of a stone weight= 2×10 N/m2
