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

A satellite is revolving round the earth in circular orbit

An artificial 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)

An artificial satellite is revolving around the earth in a circular orbit of radius r. If the time period of revolution of the satellite is T, show that T^2 prop r^3 .

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).

An artificial satellite of mass m is orbiting around the earth of mass M in an orbit of radius R, with a constant angular velocity. What is the angular momentum of a satellite ?
