A satellite of mass m is moving around the earth in a circular orbit of radius r. If the mass of the earth is M, the energy required to take the satellite to an orbit of radius 3r is

View answer and explanation

Correct option: C

\frac{{GMm}}{{3r}}

Option C (

\frac{{GMm}}{{3r}}

) is correct because the energy required is the difference in the total mechanical energy of the satellite in the two orbits.
