The charges are q1 = 17.5 nC and q2 = 25.0 nC. Point B is at the midpoint between the two charges, and point A is at the peak of an equilateral triangle, with each side of length d, as shown. (Assume the zero of electric potential is at infinity.) (a) What is the electric potential (in kV) at point A? SW (b) What is the electric potential (in kV) at point B? SW Need Help?
