1. a sphere with mass 4.00 kg and charge of
5.00 C hangs from a thread near a very large, charged insulating sheet. The
sheet is to the left of the sphere, and the sphere is is attracted toward the sheet, to the left. The charge density on the surface of the sheet is uniform and equal
1. 1: Suppose eight identical point charges q are placed at the corners of a cube with side length L.
Find the magnitude and direction of the electric force produced exerted by these charges on another
charge q at the center of a face of the cube.
3. So far...
