Question

Q.14 when some charge is transferred to...A...it readily gets distributed over the entire
surface of...A...If some charge is put on...B..., It stays at the same place
Here, A and B refer to
(a)Insulator,conductor (b)conductor,Insulator
(c)Insulator,Insulator(d.)conductor, conductor​

Answer 1

Answer:

I also think the answer shall B

Answer 2

Answer:

A is a conductor and B is an insulator. The correct option is B.

Explanation:

• Conductors: They have free electrons , which act as carrier.When   electricity is applied to it, randomly moving electrons arrange themselves in a regular order and conduct electricity. When some charge is transferred to the surface of conductor, the charge is distributed uniformly on the surface.  For example- Metals such as Iron , silver, aluminium etc.

• Insulators: Insulators lack free electrons therefore they are unable to conduct electricity. For example- Wood, paper, Non metals etc.

So from above discussion it is clear that A is Conductor and B is insulator.
