Question

Assertion (A) : When a bullet is fired from a gun, the momentum of the bullet is conserved.
Reason (R) : Law of conservation of momentum holds good for any collision.

• A. Both Assertion (A) and Reason (R) are correct and Reason(R) is the correct explanation
• B. Both Assertion (A) and Reason (R) are correct but the reason does not give the correct explanation
• C. Assertion(A) is true but Reason(R) is false
• D. Assertion(A) is false but Reason(R) is true

Answer 1

The correct option is D Assertion(A) is false but Reason(R) is true

Assertion is false because momentum of system ( gun + bullet ) as a whole is conserved not individually.
Reason is true as there is no external force on the bullet plus gun system and it holds good for any collision.
