Assertion: All surfaces shown in figure ...

Assertion: All surfaces shown in figure are smooth. System is released from rest. Momentum of system in horizontal direction is constant but overall momentum is not constant.

Reason: A net vertically upward force is acting on the system.

A

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

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

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Of the two masses A and B, mass A is moving downwards. Therefore net force on the system is vertically downwards and momentum is not conserved in vertical direction.
