What is the energy required to move a body of mass m from orbit of radius 2r to 3r?

Open in App

Solution

Potential energy, $U = G m M (\frac{1}{r_{1}} - \frac{1}{r_{2}})$

Where,

$M =$ Mass of planet.

$m =$ Mass of revolving satellite.

Energy required to move a body of mass m from orbit of radius 2r to 3r

$U = G m M (\frac{1}{2 r} - \frac{1}{3 r}) = \frac{G M m}{6 r}$

Hence, energy required is $\frac{G M m}{6 r}$
