The amount of work done to raise a mass 'm' from the surface of the Earth to a height equal to the radius of the Earth 'R' will be

Solution & Explanation

Related Formula
W = U₂ - U₁ = -(GMm)/(R+h) - (-(GMm)/(R))
Core Logic

For h = R:

W = -(GMm)/(2R) + (GMm)/(R) = (GMm)/(2R) = (mgR)/(2)
Pattern Recognition

Work done against gravity for height comparable to Earth radius.
