Question

Which one of the following plots represents the variation of gravitational field on a particle with distance r due a thin spherical shell of radius R?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Gravitational field due to the spherical shell inside the shell

F = 0 [r < R]

On surface of shell

$F=\frac{GM}{R^2}$ [r > R]

Outside the shell

$F=\frac{GM}{r^2}$ [r > R]
