Energy required to move a body of mass \(\mathrm{m}\) from an orbit of radius \(2 R\) to \(3 R\) is :
1 \(\mathrm{GMm} / 12 \mathrm{R}^2\)
2 \(\mathrm{GMm} / 3 \mathrm{R}^2\)
3 \(\mathrm{GMm} / 8 \mathrm{R}\)
4 \(\mathrm{GMm} / 6 \mathrm{R}\)
Explanation:
Change in potential energy in displacing a body from \(r_1\) to \(r_2\) is given by \( \Delta \mathrm{U}=\mathrm{GMm}\left=\operatorname{GMm}\left(\frac{1}{2 R}-\frac{1}{3 R}\right)=\frac{G M m}{6 R} \)
