A particle is kept on the surface of a uniform sphere of mass and radius . The work done per unit mass against the gravitational force between them is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Work done by a conservative force is the change in potential energy, therefore, W=Uf-Ui Now, the gravitational potential energy per unit mass or gravitational potential of the particle is, V=-GMr So, the initial potential energy,…
