A stone of mass m tied to a rope is rotated in a vertical circular path of radius r with uniform speed v. The total force required to maintain this motion acting towards the center at the lowest point is expressed as:

What force is used to remove cream from milk?

In uniform circular motion, why does the centripetal force do no work on the body?

A body of mass 'm' is moving uniformly along a circle having radius 'r' with velocity 'v'. The centripetal force on the body is:
