Find the binding energy of a satellite of mass `m` in orbit of radius `r`, (R = radius of earth, g = acceleration due to gravity)

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

The binding energy of an object of mass m placed on the surface of the earth r is (R = radius of earth, g = acceleration due to gravity)

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. )

A satellite of mass m is moving in a circular or orbit of radius R around the earth. The radius of the earth is r and the acceleration due to gravity at the surface of the earth is g. Obtain expressions for the following : (a) The acceleration due to gravity at a distance R from the centre of the earth (b) The linear speed of the satellite (c ) The time period of the satellite
