1. Two charges are set on the x-axis 9.90 cm away from each other. The charges are -8.40 nC and 18.3 nC. Calculate the electric potential at the point on the x-axis where the electric field due to these two charges is zero.

2. What is the electric potential at the point on the axis which is at x = 3.20 m. The length of the rod is L = 1.90 m and the charge on the rod is Q = 8.70 nC.
