research satellite is to be shifted from a circular orbit of radius

2R_{\oplus}

to another circular orbit of radius

3R_{\oplus}

about Earth. Using

M_{\oplus}=5.97\times10^{24}\,\text{kg}

R_{\oplus}=6.37\times10^{6}\,\text{m}

and

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

, determine the minimum work that must be done on the satellite to accomplish this transfer.
