If a body of mass

m

has to be taken from the surface of the earth to a height

h=4 R

, then the amount of energy required is (

R=

radius of the earth)

View answer and explanation

Correct option: C

\frac{4 m g R}{5}

Option C (

\frac{{4 m g R}}{{5}}

) is correct because it represents the difference in gravitational potential energy between the surface and the height h=4R.
