Question

In the figure at the right, a non-conducting rod of length L = 12.0 cm has a charge –q = –3.24 fC uniformly distributed along its length. Point P is at a distance a = 8.15 cm from the rod.

(a) What is the linear charge density of the rod?

(b) What is the magnitude of the electric field produced at point P?

(c) What is the direction (relative to the positive direction of the x-axis) of the electric field produced

at point P?

These are my teachers requirements if you could please follow them I would really appreciate it thank you J

In addition to being neat and clear, and actually answering the question, you must:

1) show the original principle (often in equation form)

2) substitute variables as needed
3) solve it first (before substituting numbers)

4) show every substitution (with units and correct sig figs)

5) present a boxed answer (with units and correct sig figs)

In a Force problem in more than one dimension, you MUST start with a Free Body Diagram.
