In Fig. 22-54, 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 we use to replace the rod? (At that distance, the rod "looks" like a particle.)
