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 assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are truebut reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) A central force is always directd 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 particular under the central force the angular momentum is always conserved. From this, it follows that the motion of a particular under the central force is always confined to a plane.
