4.4. Particles A and B, each carrying a charge of 2.0nC, are at the base corners of an equilateral triangle 2.0m on a side.
(a) What is the potential (relative to zero at infinity) at the apex of the triangle?
(b) How much work is required to bring a positively charged particle carrying a charge of 5.0nC from infinity to the apex if A and B are held fixed?
(c) Answer parts (a) and (b) for the case where particle B is replaced by a particle carrying a charge of -3.0nC.
(d) Calculate the electric potential energy for each of the two triangular charge distributions.
