Three charges, each of magnitude q, are placed at the corners of an equilateral triangle of sides a. Two of the charges are negative and one is positive.

a) What work does the electric field have to do as these charges are assembled from infinity, without acceleration?

b) What work would you have to do to now move the negative charge back to infinity?
