Two positive point charges each with charge Q = 4e where e is the magnitude of the charge on the electron are attached by a thin insulating string of length l that is not charged. For all of the following questions take V = 0 at an infinite distance from the origin, and write your answers in terms of e, l and k or epsilon0.

This is not the image, assume charges are equal distance from the origin while on the x-axis.
Write an expression for the electric potential due to these charges for a point on the y axisand an expression for the electric potential due to these charges for a point on the x axis
