STANDARD Physics Potential Energy MCQ Question

Type: MCQ-numerical-Medium-Class 11

The change in potential energy when a body of mass m is raised to a height nRₑ from Earth's surface is (Rₑ = radius of the Earth)

A

mgRen(n1)mgRₑ \frac{n}{(n-1)}

B

mgRₑ

C

mgRen(n+1)mgRₑ \frac{n}{(n+1)}

D

mgRe1nmgRₑ \frac{1}{n}

Correct Answer

Option A

Detailed Explanation

The change in potential energy is calculated using the formula for gravitational potential energy difference: Δ\Delta U = mgRₑ \left(\frac{n}{n-1}\right). This accounts for the change in height from the Earth's surface to nRₑ.
