An object of mass $\displaystyle 1$ kg is taken to a height from the surface of earth which is equal to three times the radius of earth. The gain in potential energy of the object will be [If, $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ and radius of earth $\displaystyle =6400 \mathrm{~km}$ ]
Official answer
(1)
$\displaystyle 48$ MJ
