How much work is done in circulating a small object of mass m around a sphere of mass m in a circle of radius R.

How much work is done on a body of mass m in moving it around a horizontal circle of radius R?

How much work is done on a body of mass 1 kg whirling on a circular path of radius 5m?

What is the work done on a body of mass m moving around a horizontal circle of radius r?

A particle of mass M is revolving along a circule of radius R and nother particle of mass m is recolving in a circle of radius r . If time periods of both particles are same, then the ratio of their angular velocities is
