  1. The distance between an infinite planar sheet, uniformly charged with +10nC/, and a -5.0 nC point charge is 4.0 cm.
  1. Calculate the electric force on the point charge and indicate its direction.
  2. Determine the location(s), if any, where the electric field vanishes.

c. If the point charge is free to move, calculate its speed when it strikes the sheet. Please use conversation of energy. The mass of the point charge is 2.0 mg. Neglect gravity

A uniformly charged insulating sphere (R1 = 3.0 cm) is charged to QI = 50 nC. It is concentric within a charged conducting shell (inner radius R2 = 5.0 cm, outer radius R3 = 5.2 cm) that is charged to QC = 200 nC. The insulating sphere is not connected to the conducting shell, and the conductors are separated by air. (Note: The figure is not to scale.) In which region(s) is the electric field zero, if any?

There is an infinite, uniformly charged circular sheet with a circular hole in its center. The charge per unit area is σ. The radius of the hole is R. (If you need to, you can describe the radius R∞, which you then take to infinity.) Point charge q moves from above the hole, at height Z, downwards to the center of the hole, at z = 0. Find the change in electrostatic potential energy of the point charge. Give your...
