Question
A charge + q is fixed at each of the points x = x0, x = 3x0, x = 5x0 ...... ∞ on the x-axis and charge - q is fixed at each of the points x = 2x0, x = = 40, x = 60 .... ∞ Here, x0 is a positive constant. Take the electric potential at a point due to charge Q at a distance r from it to be Q/4πε0r. Then the potential at the origin to the above system of charge is
