The three charges $\displaystyle \mathrm{q} / 2, \mathrm{q}$ and $\displaystyle \mathrm{q} / 2$ are placed at the corners $\displaystyle \mathrm{A}, \mathrm{B}$ and C of a square of side ' $\displaystyle a$ ' as shown in figure. The magnitude of electric field ( $\displaystyle E$ ) at the corner $\displaystyle D$ of the square, is :
Official answer
(1)
$\displaystyle \frac{\mathrm{q}}{4 \pi \epsilon_0 \mathrm{a}^2}\left(\frac{1}{\sqrt{2}}+\frac{1}{2}\right)$
