Find which electric field potential may be calculated at point P?

\fA rod of length I, located along the x axis has a total charge Q and a uniform linear charge density 2.. Find the electric potential at a point P located on the y axis a distance a from the origin \fWhat if you were asked to find the electric field at point P ? Would that be a simple calculation? V=k =In 1 +Va +12 - a P a dq X O X dx e
