  • The gravitational force between a hollow spherical shell and a point mass is F. Show the nature of F vs r graph where r is the distance of the point from the centre of the hollow spherical shell of uniform density.

The gravitational force between a hollow spherical shell and a point mass is F. Show the nature of the F vs r graph where r is the distance of the point from the center of the hollow spherical shell of uniform density.

Answers (1)

The gravitational force inside the hollow spherical shell is 0 and on the surface is F_{0}

F_{0}=\frac{GmM}{r^{2}} for  r\ge R and F_{0}=0 for 0<r<R
