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.
