Question

1.The pressure exerted by a cube of side 0.03m on a surface is 10Pa. Calculate the thrust exerted by the cube?

Answer 1

Answer:

Side of cube = 0.03 m  

Hence, area = 0.03 X 0.03 = 0.0009 m².     (as area of cube is side²)

Pressure = 10 Pa.

As we know that thrust is force acting per unit area.

So, thrust = force.

and force = pressure X area

So,  

= 10 X 0.0009

= 0.009 Pa.

Hence, the thrust exerted by the box is 0.009 Pa.
