Assertion (A): A ball connected to a string is in circular motion on a frictionless horizontal table and is in equilibrium.

Reason (R) : Magnitude of the centripetal force is equal to the magnitude of the tension in the string.

The correct answer is

View answer and explanation

Correct option: B

Both (A) and (R) are true but (R) is not the correct explanation of (A)

Option B (Both (A) and (R) are true but (R) is not the correct explanation of (A)) is correct because the ball is in uniform circular motion, implying a net force, so it's not in equilibrium, but the tension provides the centripetal force.
