A satellite of earth of mass 'm' is taken from orbital radius 2R to 3R, then minimum work done is :-

A satellite of mass 'm' is revolving in an orbit of radius 2 R. The minimum energy required to lift it into another orbit of radius 3R is (R is radius of the earth and g is acceleration due to gravity on its surface. )

If an object of mass m is taken from the surface of earth (radius R) to a height 5R, then the work done is

If an object of mass m is taken from the surface of earth (radius R) to a height 5R, then the work done is

An artificial satellite of mass m is revolving round the earth in a circle of radius R . Then work done in one revolution is

The binding of a satellite of mass m in a orbit of radius r is

An aritificial satellite of mass m is moving round the earth, in an orbit of radius 2R. How much work is to be done to transfer the satellite to an orbit of radius 4R? How will the potential energy of the satellite change? (R = Radius of earth).
