In this worksheet, we will practice calculating the resultant electric fields produced by multiple charges and their vectors.
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?
- A =
- B =
- C =
- D =
- E =
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 ?
- A N/C
- B N/C
- C N/C
- D N/C
- E N/C
What magnitude force would act on a charge if it was located at ?
Point charges are placed at the four corners of a rectangle as shown. The charges’ magnitudes are: What is the electric field in the plane of the rectangle at the point ?
