In the figure below, a nonconducting rod of length L = 7.50 cm has charge -q = -4.68 fC uniformly distributed along its length.
(a) What is the linear charge density of the rod?
1 _________ C/m
(b) What is the magnitude of the electric field at point P, a distance a = 12.0 cm from the end of the rod?
2 __________N/C
(c) What is its direction?
3 __________° (counterclockwise from the positive x axis)
(d) What is the electric field magnitude produced at distance a = 50 m by the rod?
4 __________N/C
(e) Repeat part (d) for a particle of charge -q = -4.68 fC that replaces the rod.
5 ___________N/C
