Positive charge, Q, is distributed evenly along the y-axis between y=0 and y=a. A negative charge, -q is located on the x-axis a distance x from the rod.
(a) Find the electric field at the location of the negative charge.
(b) Find the potential at the location of the negative charge.
(see attached file for diagram)
This solution provides step-by-step calculations for finding the electric field and potential at the location of a negative charge located a distance away from positive charge.
