The energy required to take a satellite ...

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 :
