question on the side.
5 20 points A disk of radius R = 3.4 m carries a charge Q = 9 nC on its surface. The charge is distributed uniformly. What is the value of the potential created by the disk at a point located a distance z = 8.4 m? Round off your answer to one decimal place but do not include the unit.
Line of charge A plastic rod is placed along the horizontal from x = -2.0 m to x = 2.0m. A charge Q = 5 nC is spread uniformly along the line. Use this information to answer each of the Line of charge A plastic rod is placed along the horizontal from x = -2.0 m to x = 2.0m. A charge Q = 5 nC is spread uni
