A satellite of mass

1000\,\text{kg}

is moved slowly from a circular orbit of radius

8\times10^{6}\,\text{m}

to another circular orbit of radius

12\times10^{6}\,\text{m}

around the Earth. Taking the Earth’s mass as

6.0\times10^{24}\,\text{kg}

, calculate the change in the satellite’s gravitational potential energy. (Take

G = 6.67\times10^{-11}\,\text{N\,m}^2\text{/kg}^2
