Consider a uniformly charged ring with a total charge q. The plane of the ring is in the xy plane and has its center on the z axis. The potential at a distance z from the center of the ring and along the axial line is kq then given by the expression V = where k is Coulomb's constant. Use this information to find the electric field for q = 3.75 C, R = 1.30 m, and z = 0.350 m. z + R 2.51e4 1 x T Review rules for differential calculus. Check your input values and calculation.
