Assertion: The motion of a particle under the central force is always confined to a plane.
Reason: Angular momentum is always conserved in the motion under a central force.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
A central force is always directed towards or away from a fixed point, along the point of application of the force with respect to the fixed point. In motion of a particle under the central force the angular momentum is always coserved. From this, it follows that the motion of a particle under the central force is always confined to a plane.
