We study the three point charges shown in the figure. They are held at the corners of an equilateral triangle with ℓ = 0.7 m. What is the electric potential energy (in J) of the system of three point charges? Use for the three charges q1 = +2Q, q2 = −3Q, and q3 = +Q, where Q = 104 nC. Hint: The solution is done in steps. Assume that you first bring one of the point charges from a very large (infinite) distance to its position, then repeat this procedure for the second and third point charges.
