Electric Potential Energy of a Charge System

Question

Four identical charges $$q$$ are positioned at the corners of a square with side length $$d$$. The electric potential energy of a pair of charges separated by a distance $$r$$ is given by $$kq^2/r$$. What is the total electric potential energy of this system of charges?

Accepted Answer

$$4kq²/d + 2kq²/(d\sqrt{2})$$

Answer

$$4kq²/d$$

Answer

$$2kq²/d + 2√2kq²/d$$

Answer

$$6kq²/d$$
