Question

Assertion: There is a resistance offered by an object to change its state of motion.
Reason: The mass of an object is a measure of its inertia.

• 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 wrong statements

Answer 1

The correct option is B

Both assertion and reason are correct statements but the reason is not the correct explanation of the assertion.

The explanation for the assertion statement:

1. The resistance offered by an object to change its state of motion is called inertia.
2. Inertia is the property by virtue of which it resists any change in its state of rest or motion.

The explanation for the reason statement:

1. The inertia of an object depends upon its mass.
2. An object which has more mass will have more inertia as compared to an object which has less mass.

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

Hence option B is the correct answer.
