A metal sphere is electronically neutral and mounted on an insulating support rod. A small amount of negative charge is then placed at point A on the sphere. Which statement is true?

A. The excess charge is uniformly distributed inside the sphere.

B. The excess charge has distributed itself uniformly over the surface of the sphere.

C. Most of the charge is still at point A, but some will have spread over the sphere.

D. All of the excess charge remains around point A.

E. There will be no excess charge left a few seconds later.

Metal sphere A, with a radius RA = 2.00 mm, is fixed at the origin. A smaller metal sphere B (mB = 10.0 grams, RB = 1.00 mm) is tethered to sphere A by a thin, taut conducting string that is 1.00 m long, connecting the surface of A to the surface of B. A total charge of 9.00 C is placed on the connected spheres. (a) Assuming no charge remains on the thin string, determine how the 9.00 C...
