PhysicsEasysingle choice

The additional kinetic energy to be provided to a satellite of mass $m$ revolving around a planet of mass $M$ , to transfer it from a circular orbit of radius $R_{1}$ to another of radius $R_{2} (R_{2} > R_{1})$ is

Options:

Answer:

Solution:

The kinetic energy changing the orbit of satellite $KE = (- \frac{GMm}{2 R _{2}}) - (- \frac{GMm}{2 R _{1}}) KE = \frac{GMm}{2} [\frac{1}{R _{1}} - \frac{1}{R _{2}}]$
