If one wants to remove all the mass of the earth to infinity in order to break it up completely.
The amount of energy that needs to be supplied will be $\displaystyle \frac{x}{5} \frac{\mathrm{GM}^2}{\mathrm{R}}$ where $\displaystyle x$ is \_\_\_\_
(Round off to the Nearest Integer)
(M is the mass of earth, R is the radius of earth, G is the gravitational constant)
