JEE Main Physics question

A particle of mass is placed inside a spherical shell, away from its centre. The mass of the shell is .

(A)The particle will move towards the centre if , and away from the centre if
(B)The particle will move towards the centre
(C)The particle will oscillate about the shell
(D)The particle will remain stationaryCorrect

Answer: (D)

Solution

By the shell theorem, the gravitational field strictly inside a uniform spherical shell is exactly zero at every interior point, regardless of the shell's mass or the particle's own mass. So no net gravitational force acts on the particle
