A non-conducting solid sphere has volume charge density that varies as `rho=rho_(0)` r, where `rho_(0)` is a constant and r is distance from centre. Find out electric field intensities at following positions.
(i) `r lt R" "`(ii) `r ge R`

Explanation

To find the electric field intensity at different positions in a non-conducting solid sphere with a volume charge density that varies as \(\rho = \rho_0 r\), we will use Gauss's Law. Let's solve the problem step by step.

### Step 1: Understanding the Charge Density
The charge density is given as:
\[ \rho(r) = \rho_0 r \]
where \(\rho_0\) is a constant and \(r\) is the distance from the center of the sphere.
