Intensity due to spherical shell inside the surface I=0 Gravitational field F= textIm F=0 × m=0 F=0

Q. A point mass is placed inside a thin spherical shell of radius $H$ and mass $M$ at a distance $R /2$ from the centre of the shell. The gravitational force exerted by the shell on the point mass is.

$\frac{GM}{- 2 R ^{2}}$

$\frac{GM}{2 R ^{2}}$

zero

$\frac{GM}{4 R ^{2}}$

Intensity due to spherical shell inside the surface $I = 0$
Gravitational field $F = Im$
$F = 0 \times m = 0$
$F = 0$
