Question

Que. 16.(i)If a weight of 150 N is applied on a surface of area 10cm X
10cm, calculate the pressure acting on the surface.
(i) What happens to the atmospheric pressure when one goes
to higher altitudes.
​

Answer 1

Answer:

Given:-

Weight of object = 150 N

Surface Area = 10×10 cm = 10×10/100 m

= 1 m

To Find:-

Pressure acting on the object

Sol;

Pressure of a given object

= Area of object in metre/Weight in Newton

= N/m²

= 1/150 N/m². ans......
