A particle of mass m is located at a distance r from the centre of a shell of mass M and radius R. The force between the shell and mass is F(r). The plot of F(r) vs r is. |

$\Rightarrow F=\left\{\begin{array}{l}\frac{\mathrm{GMm}}{\mathrm{r}^2}, \mathrm{r} \geq \mathrm{R} \\ ~~0, ~~~~\mathrm{r}<\mathrm{R}\end{array}\right.$ |
