Three charges q, -q, q placed at the vertices of an equilateral triangle as shown in figure. What is the magnitude of force on charge placed at position 3 due to the presence of other two charges?
|
$\frac{1}{2 \pi \varepsilon_{o}} \frac{q^2}{l}$ $\frac{\sqrt{3}}{4 \pi \varepsilon_{o}} \frac{q^2}{l^2}$ $\frac{\sqrt{5}}{8 \pi \varepsilon_{o}} \frac{q}{\sqrt{l}}$ $\frac{1}{4 \pi \varepsilon_{o}} \frac{q^2}{\sqrt{l}}$ |
$\frac{\sqrt{3}}{4 \pi \varepsilon_{o}} \frac{q^2}{l^2}$ |
The correct answer is Option (2) → $\frac{\sqrt{3}}{4 \pi \varepsilon_{o}} \frac{q^2}{l^2}$ |
