Q36:A packed bundle of long, straight, insulated wires forms a cylinder of radius R = cm. If each wire carries A, what are
(a) the magnitude and
(b) the direction of the magnetic force per unit length acting on a wire locatedcm from the center of the bun- dle?
(c) What If? Would a wire on the outer edge of the bundle experience a force greater or smaller than the value calculated in parts (a) and (b)? Give a qualitative argument for your answer.
