Question: (a) A total charge Q = 60C is split into two equal charges located at 180 intervals around a circular loop of radius 4 m.

(a) A total charge Q = 60µC is split into two equal charges located at 180° intervals around a circular loop of radius 4 m. Find the potential at the center of the loop.
(b) If Q is split into three equal charges spaced at 120° intervals around the loop, find the potential at the center.
(c) If in the limit ρL = Q/8π, find the potential at the center.
