Which one of the following plots represents the variation of gravitational field on a particle with distance $r$ due to a thin spherical shell of radius $R$ ? ( $r$ is measured from the centre of the spherical shell).
Solution
Inside the shell, $E=0$ and outside the shell, $E \propto \frac{1}{r}$
Hence, graph (b) shows the exact result.
