The change in the gravitational potential energy when a body of a mass

1.	The change in the gravitational potential energy when a body of a mass `m` is raised to a height `nR` above the surface of the earth is (here `R` is the radius of the earth)A. `m g R((n)/(n - 1))`B. `n m g R`C. `mgR((n^(2))/(n^(2) + 1))`D. `mgR((n)/(n + 1))`
Answer» Correct Answer - D Change in potential energy, `DeltaE = GMn((1)/(R ) - (1)/(R + nR)) = (GM m)/(R(R + nR)) xx nR` `= (GMm)/(R ) ((n)/(1 + n)) = gRm ((n)/(1 + n))`
