A spherically symmetric charge distribution is considered with charge density varying as $$\rho(r)= \begin{cases}\rho_0\left(\frac{3}{4}-\frac{r}{R}\right) & \text { for } r \leq R \\ \text { zero } & \text { for } r>R\end{cases} $$ Where, $\displaystyle \mathrm{r}(\mathrm{r}<\mathrm{R})$ is the distance from the centre O (as shown in figure). The electric field at point $\displaystyle P$ will be :
