Draw the electric field inside a uniformly-charged nonconducting sphere of total charge Q and radius R.

2. Relevant equations

[tex]

\begin{align*}

E &= \frac{Q}{r^2} \quad (r \geq R)\\

E &= \frac{Qr}{R^3} \quad (r < R)

\end{align*}

[/tex]

3. The attempt at a solution

I don't know how to draw the field inside the sphere. The number of field lines should increase as one goes from zero to R, so that if one draws spheres of increasing radii inside the nonconducting sphere, there should be more and more field lines. My best guess is shown in the attachment.
