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=-\frac{GM}{r}] $ =constant and $ [E=0] $

    Outside the shell, $ [v=-\frac{GM}{r}and,,E=\frac{GM}{r^{2}}] $

    As r increases, increases and E decreases.
