Lesson: Calculating the Net Electric Field of Multiple Point ChargesPhysics
In this lesson, we will learn how to calculate the resultant electric fields produced by multiple charges and their vectors.
Sample Question Videos
Two equally 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 ?
Two fixed point charges each have magnitudes of C. The charges are located on the -axis at the positions and . A charge is placed at the origin and the resultant electric field of the three charges is zero at a point on the -axis where . Find the magnitude of .
