Two equal sized charged spheres, Sphere A and Sphere B have charges of and respectively. The spheres are separated by a straight-line distance . The net electric field produced by spheres has a null point along at a distance of m from Sphere A. What is the ratio of the magnitude of the charge of Sphere B to that of Sphere A?
Point charges and are placed 1.0 m apart. The point is at the midpoint of the two charges’ positions.
What is the magnitude of the electric field produced by the charges at ?
What magnitude force would act on a charge if it was located at ?
