Q14

A $500\ \mathrm{kg}$ satellite is initially in a circular orbit with a radius of $10\,000\ \mathrm{km}$ around the Earth. The satellite is then moved to a new circular orbit with a radius of $20\,000\ \mathrm{km}$.

What is the change in the gravitational potential energy of the satellite?
A. $1.5\times10^{3}\ \mathrm{J}$
B. $1.5\times10^{9}\ \mathrm{J}$
C. $1.0\times10^{10}\ \mathrm{J}$
D. $1.0\times10^{13}\ \mathrm{J}$
