A body of mass m is moving in a circle of radius r with a constant speed v, The force on the body is `(mv^(2))/(r )` and is directed towards the centre what is the work done by the from in moving the body over half the circumference of the circle?

A body of mass m is moving in a circle of radius r with a constant speed v, The force on the body is (mv^(2))/(r ) and is directed towards the centre. What is the work done by the force in moving the body over half the circumference of the circle?

A body of mass m is moving in a circle of radius 'r' with a constant speed v. The force on the body is (mv^(2))/(r) and is r directed towards the center. If work done by this force in moving the body over half the circumference and complete circumference is W and W', then:
