Physics-Gravitational Potential Energy
NEET Physics Gravitational Potential Energy MCQ Question
Type: MCQ-numerical-Medium-Class 11
A satellite of mass 500 kg is in a circular orbit at a radius of 3R_E from the center of the Earth. What is the change in gravitational potential energy when it is moved to a radius of 5R_E?
A
5.33 × 10^9 J
B
20 × 10^9 J
C
13 × 10^9 J
D
07 × 10^9 J
Correct Answer
Option B
Detailed Explanation
The change in gravitational potential energy is given by the formula ΔV = V_f - V_i, where V = -GM_E m / r. Calculating for both orbits and finding the difference gives the result.
