Question

A spherically symmetric charge distribution is considered with charge density varying as

Where, r(r < R) is the distance from the centre O (as shown in figure). The electric field at point P will be :

Select the correct option:

$\frac{\rho_0 r}{4 \varepsilon_0}\left(\frac{3}{4}-\frac{r}{R}\right)$

$\frac{\rho_0 r}{3 \varepsilon_0}\left(\frac{3}{4}-\frac{r}{R}\right)$

$\frac{\rho_0 r}{4 \varepsilon_0}\left(1-\frac{r}{R}\right)$

$\frac{\rho_0 r}{5 \varepsilon_0}\left(1-\frac{r}{R}\right)$

✓ Correct! Well done.
