1) Positive charge Q is placed on a conducting sphereical shell with inner radius R1 and outer radius R2. A point charge q is placed at the center of the cavity. The magnitude of the electric field at a point outside the shell, a distance r from the center is:

2) Positive charge Q is placed on a conducting sphereical shell with inner radius R1 and outer radius R2. Apoint charge q is placed at the center of the cavity. The magnitude of the electric field produced by the charge on the inner surface at a point in the interior of the conductor a distance from the center is:

3) Charge is distributed uniformally on the surface of a large flat plate. The electric field 2cm fom the plate is 30N/C. The electric field 4cm from the plate is:
