1. Problem Statement
A uniformly charged rod of length L and total charge Q lies along the x-axis as shown in in the figure below. (Use the following as necessary: Q, L, d, and ke.)
(a) Find the components of the electric field at the point P on the y-axis a distance d from the origin.
(b) What are the approximate values of the field components when d >> L?
2. Equations
I have a diagram and understand that E=kQ/r^2, however, I can not figure out how to define each component.
3. Attempt
I know that I must integrate to solve once I have defined the component, however I do not know how to define them.
Would Ex=rsin(θ)[(kQ)/r^2] and Ey=rcos(θ)[(kQ)/r^2] be at all in the right direction?
