Question

Directions: In the following questions, a statement of assertion is followed by a statement of reason.

Mark the correct choice as:

(a) If both assertion and reason are true and reason is the correct explanation of assertion.

(b) If both assertion and reason are true but reason is not the correct explanation of assertion.

(c) If assertion is true but reason is false.

(d) If assertion is false but reason is true.

1. Assertion: Displacement is a vector quantity.
2. Reason: It is the shortest distance between the initial and final position of body.

Answer 1

Explanation for assertion statement

1. Displacement is a vector quantity.
2. It has both magnitudes as well as directions.
3. It follows vector laws.

Explanation for reason statement

1. Displacement is the shortest distance between the initial and final position of the body.
2. If the body traveled with the initial and final point same, displacement of the body is zero.

Therefore, both assertion and reason are true but reason is not the correct explanation of assertion.

Hence, option (b) is the correct answer.
