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

As shown in the below figure

If Gravitational field Intensity due to uniform solid sphere= I

Then  Inside surface  I.e  for  $r

$I= \frac{GMr}{R^{3}}$

Where

$R\rightarrow$ Radius of shell

$r\rightarrow$ Position of Pt.

$M\rightarrow$ Mass of Solid sphere
