Let E be the energy required to raise a satellite to height h above earth's surface and E' be the energy required to put the same satellite into orbit at that height. Then E//E' is equal to

Taking the earth to be a uniform sphere of radius 6400 km and the value of g at the surface to be 10ms^(-2) , calculate the energy needed to raise a satellite of mass 2000 kg to a height of 800 km a above the earth's surface and to set it into circular orbit at that altitude.

What is the energy required by a satellite to keep it orbiting?

The energy required to take a satellite to a height ‘h’ above Earth surface (radius of Earth =6.4xx10^3 km ) is E_1 and kinetic energy required for the satellite to be in a circular orbit at this height is E_2 . The value of h for which E_1 and E_2 are equal, is:
