Question

What is the amount of work done on a body of mass 10 g moving in a circular path of radius 5 cm?

Answer 1

Answer:

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.

Answer 2

Answer:

The work done on a body moving in a circular path is zero, because when a body moves in a circular path then thek centripetal force acts along the radius of the circle and it is at right angles to the motion of the body.
