A nonconducting solid sphere of radius 2.20 cm carries a uniformly distributed positive charge of 7.20×10-9 C. Calculate the magnitude of the electric field at a point 1.80 cm away from the center of the sphere. Tries 0/12 Calculate the magnitude of the electric field at a point 3.70 cm away from the center of the sphere. Tries 0/12 Assume that the sphere is conducting. Calculate the magnitude of the electric field at a point 1.80 cm away from the center of the sphere. Tries 0/12 Calculate the magnitude of the electric field for the conducting sphere at a point 3.70 cm away from the center of the sphere.
