How Gravitational Potential due to uniform solid sphere of radius R varies with the distance r from its center (For r< R) ??

Answers (1)

As shown in the below figure

If Gravitational Potential due to uniform solid sphere= V

Then  For Inside surface  I.e  for  r<R

        V=-\frac{GM}{2R}\left[3-\left ( \frac{r}{R} \right )^{2}\right]

R\rightarrow Radius of shell

r\rightarrow Position of Pt.

M\rightarrow Mass of Solid sphere
