Question

A metallic sphere A of radius 1.00 cm is several centimeters away from a metallic spherical shell B of radius 2.00 cm. Charge 450 nC is placed on A, with no charge on B or anywhere nearby. Next, the two objects are joined by a long, thin, metallic wire (as shown in the figure below), and finally the wire is removed. How is the charge shared between A and B?

A metallic sphere A of radius 1. 00 cm is several centimeters away from a metallic spherical shell B of radius 2. 00 cm. Charge 450 nC is placed on A, with no charge on B or anywhere nearby. Next, the two objects are joined by a long, thin, metallic wire (as shown in the figure below), and finally the wire is removed. How is the charge shared between A and B? (ii) A metallic sphere A of radius 1 cm with charge 450 nC hangs on an insulating thread inside an uncharged thin metallic spherical shell B of radius 2 cm. Next, A is made temporarily to touch the inner surface of B. How is the charge then shared between them? Choose from the same possibilities.

Explanation / Answer

1) answer 150 nC on A and 300 nC on B
