MCQ
Let there be a spherically symmetric charge distribution with charge density varying as $\text{p}(\text{r})=\text{p}_0\bigg(\frac{5}{4}-\frac{\text{r}}{\text{R}}\bigg)$ upto r = R and p(r) = 0 for r > R where r is the distance from the origin the electric field at a distance r(r < R) from the origin is given by.
- A$\text{p}{_0}^\text{r}\Big(\frac{5}{3}-\frac{\text{r}}{\text{R}}\Big)$
- B$\frac{4\pi\text{p}{_0}^\text{r}}{3\in_0}\Big(\frac{5}{3}-\frac{\text{r}}{\text{R}}\Big)$
- C$\frac{4\text{p}{_0}^\text{r}}{4\in_0}\Big(\frac{5}{4}-\frac{\text{r}}{\text{R}}\Big)$
- D$\frac{\text{p}{_0}^\text{r}}{3\in_0}\Big(\frac{5}{4}-\frac{\text{r}}{\text{R}}\Big)$
