Question
For two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
  1. Both A and R are true, and R is the correct explanation of A.
  2. Both A and R are true, but R is not the correct explanation of A.
  3. A is true, but R is false.
  4. A is false, and R is also false.
Assertion (A): Two adjacent conductors, carrying the same positive charge have no potential difference between them.
Reason (R): The potential of a conductor does not depend upon the charge given to it.

Answer

  1. A is false, and R is also false.

Explanation:

The potential of a conductor depends upon the charge given to it and there exist a potential different between two adjacent conductors.
