Problem

The energy required to take a satellite to a height 'h' above Earth surface (radius of Earth =

6.4 \times 10^3

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: [Main 9 Jan. 2019 III] a.
