Question

Assertion: Two different physical quantities, the distance and the displacement are used to describe the overall motion of an object.

Reason: The distance gives the magnitude and the displacement gives the magnitude and direction of the body.

• A. Both assertion and reason are correct statements, but the reason is the correct explanation of the assertion.
• B. Both assertion and reason are correct statements, but the reason is not the correct explanation of the assertion.
• C. The assertion is correct but the reason is the wrong statement.
• D. The assertion is wrong but the reason is the correct statement.
• E. Both assertion and reason are the wrong statements.

Answer 1

The correct option is A

Both assertion and reason are correct statements, but the reason is the correct explanation of the assertion.

The explanation for the assertion:

1. The motion of an object is described by the change in its position according to time.
2. It is described by the two values, distance, and displacement.

The explanation for the reason:

1. The length of the path travelled by an object is called distance.
2. It is a scalar quantity that has a magnitude, but not a direction.
3. During the motion, the minimum distance between the initial and final positions of the object is called displacement.
4. It is a vector quantity and has both magnitude and direction.

Hence, the correct answer is (A) Both assertion and reason are correct statements, but the reason is the correct explanation of the assertion.
