As we learn

Intensity due to spherical shell -

R\rightarrow Radius of shell

r\rightarrow Position of Pt.

M\rightarrow Mass of spherical shell

- wherein

Outside the surface r>R

I= \frac{GM}{r^{2}}

on the surface

r=R

I= \frac{GM}{R^{2}}

inside the surface 

  r<R

I=0

 

 If     r> R\: \: \: Eg=\frac{GM}{r^{2}}

If     r= R \: \: \: Eg=\frac{GM}{R^{2}}

If     r< R\: \: \: Eg=0
