Question

Assertion : A five rupee coin has more inertia than one rupee coin. 01

Reason : Inertia does not depend upon mass of the object.​

Answer 1

Answer :

• Here , Assertion is true but reason is not correct and false too .

★ Option c is correct in such cases .

• Explanation :

→ Inertia depends on mass . Therefore , reason given is totally wrong .

→ Generally a five rupee coin is heavier than the one rupee coin , which means the five rupee coin has more mass , thus more inertia .

Answer 2

Assertion is correct but reason is false.

Explanation:

• Newton's first law states that any object at rest will remain at rest and any object in motion will stay in motion unless an external force is applied to it. This is also called law of inertia.

• Inertia is the property of a body to resist any change in its state.

• It depends on the mass of the body.
• When mass is large, the tendency to resist change in its state becomes more and so more force will be required for any state change.

A five rupee coin has more mass than one rupee coin and so it has more inertia than that of one rupee coin.
