Anonconducting rod of length l = 8.15 cm has charge –q = -4.23 fc uniformly distributed along its length.(a) what is the linear charge density of the rod? what are the(b) magnitude and(c) direction(relative to the positive direction of the s-axis) of the electric field produced at point p, at a distance a = 12.0 cm from the rod? what is the electric field produced at point p, at distance a = 12.0 cm from the rod? what is the electric field magnitude produced at distance a = 50 m by(d) the rod and(e) a particle of charge –q = -4.23 fc that replaces the rod?
