9. Figure shows a point charge q and a thin rod of length L that is parallel to y-axis. The rod carries a uniformly distributed charge Q. Determine the total electric potential V at the origin taking V= 0 at infinity. 2d d [L+v[²+d² Answer: Vot = k + k% In *V 2d

In the figure set V = 0 at infinity and let the particles have charges q1 = +q = -5.00×10-5 C and q2 = -5q. They are seperated by d = 50 cm, with q1 located at the origin. Locate any points on the x axis (other that at infinity) at which the net potential due to the two particles in zero. What is the positive position? What is a negative position?
