# Question

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 (Fig)

(a) point P, a distance x to the right of the rod, and

(b) point R, a distance y above the right-hand end of the rod.

(c) In parts (a) and (b), what does your result reduce to as x or y becomes much larger than a?
