Electrostatic Potential Energy

Three equal $(+q)$ charges are placed in air at the vertices of equilateral triangle. If the side of equilateral triangle is $l$ , the net potential energy of the system is $\left[K = \frac{1}{4\pi\epsilon_0}\right]$

Show answer and solution

Answer: (c)

Three pairs, each at distance $l$ : $U = 3 \times \dfrac{kq^2}{l}$
So the answer is (c) $\dfrac{3kq^2}{l}$ .
