Question 136 of 311

In a uniformly charged sphere of total charge $Q$ and radius $R$, the electric field $E$ is plotted as a function of distance from the centre. The graph which would correspond to the above will be

ABCD

Show answer and solution▾

Answer: (C)

$\overrightarrow{\mathrm{E}}_{\text {inside }}=\left(\frac{1}{4 \pi \varepsilon_0} \frac{\mathrm{Q}}{\mathrm{R}^3}\right) \overrightarrow{\mathrm{r}}$
$\overrightarrow{\mathrm{E}}_{\text {outside }}\left(\frac{1}{4 \pi \varepsilon_0} \frac{\mathrm{Q}}{\mathrm{r}^3}\right) \overrightarrow{\mathrm{r}}$
$\therefore$
