Gravitation Question 335

Question: Two concentric spherical shells are as . Choose the correct statement given below.

Options:

A) Potential at A is greater than B

B) Gravitational field at A is less than B

C) As one moves from C to D then potential remains constant

D) As one moves from D to A then gravitational field decreases

Show Answer

Answer:

Correct Answer: C

Solution:

  • Inside a shell [v=GMr] =constant and [E=0]

    Outside the shell, [v=GMrand,,E=GMr2]

    As r increases, increases and E decreases.
