NEET 2026 Physics Gravitational Potential Energy MCQ Question
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
2 mg R
mg R / 4
mg R
mg R / 2
Correct Answer
Detailed Explanation
The work done is calculated using the formula W.D. = U₂ - U₁ = (GMm/2R) - (GMm/R) = GMm/2R - GMm/R = mgR/2.
