A line of charge with a non-uniform charge density =ay, where a=?400 nCm2 lies along the y axis in the region 0y110 m. Calculate the electric potential of this line of charge at point P on the x axis a distance 1.50 m from the origin. Assume the potential equals zero at infinity.
What is the total charge?
