Electric charge is distributed uniformly along a thin rod of length a, with total charge Q. Take the potential to be zero at infinity. Find the potential at the following points: P is distance x from (0,0) which is the right side of the rod.

Find the potential at the point P, a distance to the right of the rod.

In part A, what does your result reduce to as x becomes much larger than a?
