question on the side.
4 20 points What is the value of the electric potential created by a ring of charge of radius R = 0.3 m and charge Q = 5 nC at a point located a distance z =4.5 m from the center of the ring? Round off your result to 1 decimal place, but do not include the unit. Type your answer...
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
