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): Charge is quantized.
Reason (R): Charge which is less than I C is not possible.
✓

Answer

  1. A is true but R is false.

Explanation:

The charge q on a body is given as q = ne where n is any integer positive or negative. The charge on the electron is q = 1.6 × 10-19C which is less than 1C.
