Two spherical shells have masses `m `and `2m` as shows. Choose the correct options.

A

Between `A` and `B` gravitational field strength is zero

B

Between `A` and `B` gravitional potential is constant

C

There will be two points one lying between `B` and `C` and other lying between `C` and infinity when gravitational field strength are same

D

There will be a point between `B` and `C` where gravitational potential will be zero

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Inside a shell,`V =` constant and `E = 0`.
Between `A` AND `B`, `E_("net") = 0,V_("net") =` constant because these points `mu` inside both shells. ltbegt Between `B` and `C`
`E` of `m != 0`, `E of 2m = 0`
`V` of `m !=` constant, `V` of `2m =` constant.
Beyond `C`
`E` and `V` due to both shells are neither zero nor constant.
