An uncharged metal object M is insulated...

An uncharged metal object `M` is insulated from its surroundings. A positively charged metal sphere `S` is then brought neat to `M`. Which diagram best illustrates the resultant distributions of charge on `S` and `M`

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
Negative charges are attracted to surface of M near S by electrostatic induction and positive charges are repelled to surface of M away from S such that entire M still remains neutral (uncharged).
Charge on S is also redistributed to have more charge on surface near to M due to the field set up by negative charges on M.
Diagram `b` thus best illustrates the charge distribution on both `S and M`.

    Three metal spheres A,B and C are mounted on insulating stands. The spheres are touching one another, as shown in the diagram A strong positively charged object it brought near sphere A and a strong negative charge is brought near sphere C. While the charged objects remains near spheres A anc C, sphere B is removed by means of its insulating stand. After the charged objects are removed, sphere B is first touched to sphere A and then to sphere C. The resulting charge on B would be-
