Aline of a -25 mc uniformly distributed charge extends from the y 0.0 m to y 8.0 m a) at the (x, v) coordinate (4.0 m, 4.0 m), what is the electric potential due to the distribution of charge? (assume that the electric potential 0 at a point an infinite distance away from the origin.) b) what is the electric potential at (2.0m, 3.0m)? for the last part of this problem, let there be four lines of charge, each 8.0 m long with a uniformly distributed charge of -100 mc (total). these lines are put in a plane forming a square with coners at (om, om), (8m, om), (8m, 8m), (om, 8m). c) what is the electric potential at the center of the square?
