Three charged particles

$A, B$ and $C$ with charges $-4 q, 2 q$ and $-2 q$ are present on the circumference of a circle of radius $d$. The charged particles $A, C$ and centre $O$ of the circle formed an equilateral triangle as shown in figure. Electric field at $O$ along $x$-direction is:

  1. $\frac{\sqrt{3 q}}{\pi \epsilon_{0} d^{2}}$

  2. $\frac{2 \sqrt{3 q}}{\pi \epsilon_{0} d^{2}}$

  3. $\frac{\sqrt{3 q}}{4 \pi \epsilon_{0} d^{2}}$

  4. $\frac{3 \sqrt{3 q}}{4 \pi \epsilon_{0} d^{2}}$

Correct Option: 1
