Three charged particles A, B and C with charges -4q, 2q and -2q 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
\(\frac{\sqrt{3} \mathrm{q}}{4 \pi \epsilon_0 \mathrm{~d}^2}\)
2
\(\frac{3 \sqrt{3} \mathrm{q}}{4 \pi \epsilon_0 \mathrm{~d}^2}\)
3
\(\frac{2 \sqrt{3} \mathrm{q}}{\pi \epsilon_0 \mathrm{~d}^2}\)
4
\(\frac{\sqrt{3} \mathrm{q}}{\pi \epsilon_0 \mathrm{~d}^2}\)
