Question

We study the three point charges shown in the figure. They are held at the corners of an equilateral triangle with ℓ = 0.9 m. What is the electric potential energy of the system of three point charges? Use for the three charges
q1 = +2Q,

q2 = −3Q,
and
q3 = +Q,
where
Q = 101 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
