bhima was powerful enough to throw an elephant of mass m completely away from the earth .assuming the mass of earth to be M and radius R find the work done by bhima

Dear Student ,
From the theory of gravitation we know that , 
Work done is equal to the change in potential energy to bring a body from earth to any point in the infinity .
So the work done in throwing an elephant of mass m completely away from the earth whose mass is M and radius is R is , W = $\frac{GMm}{R}$
