In Figure, a nonconducting rod of length L = 8.15 cm has a 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 x axis) of 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?
