Question

Find the force applied by atmospheric pressure on area 15cm x 15cm.

Answer 1

force= pressure*area=15*15*0.0001*10000=2250N

Answer 2

Answer: The force applied by atmospheric pressure is 2279.8 N.

Explanation:

Given that,

Area $A = 15cm\times 15 cm$

We know that,

The pressure is the force per unit area.

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

$F = P\times A$

Pressure at one atm is 101325 Pa.

Now, put the value of pressure and area

$F = 101325N/m^{2}\times 0.15m\times0.15 m}$

$F = 2279.8 N$

Hence, the force applied by atmospheric pressure is 2279.8 N.
