Question
The three charges $q / 2, q$ and $q / 2$ are placed at the corners $A, B$ and $C$ of a square of side ' $a$ ' as shown in figure. The magnitude of electric field ( E ) at the comer D of the square, is ${ }_{\text {i }}$
Select the correct option:
A
$\frac{q}{4 \pi \epsilon_0 a^2}\left(\frac{1}{\sqrt{2}}+\frac{1}{2}\right)$
B
$\frac{q}{4 \pi \epsilon_0 a^2}\left(1+\frac{1}{\sqrt{2}}\right)$
C
$\frac{q}{4 \pi \epsilon_0 a^2}\left(1-\frac{1}{\sqrt{2}}\right)$
D
$\frac{q}{4 \pi \epsilon_0 a^2}\left(\frac{1}{\sqrt{2}}-\frac{1}{\sqrt{2}}\right)$
✓ Correct! Well done.
