Determine the energy required to launch a satellite of mass m from the surface of a planet of mass M and radius R in a circular orbit at an altitude of 3R.

View answer and explanation

Correct option: D

\frac{{7GMm}}{{8R}}

Option D (

\frac{{7GMm}}{{8R}}

) is correct because it calculates the energy difference between the initial potential energy and the final total energy of the satellite.
