(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]

\bold{V}\ =\ \frac{Q\,(3R^2\ -\ r^2)}{4\,\pi\,\varepsilon_0 \ \ {2R^3}}

[/tex]

Potential inside the sphere.

2. Relevant equations

Electric field inside the sphere (non conducting):

[tex]

\bold{E}\ =\ \frac{Q.r}{4\,\pi\,\varepsilon_0\,R^3}

[/tex]

and

[tex]

\bold{V}\ = \int E.dr[/tex]

In one dimension.

3. The attempt at a solution

Even when we use both the formula's I've given we don't get the one given in the book. Does anybody here have some suggestion to find, how they have derived it.
