Question
The centripetal force required to keep an object in circular motion is given by:
Correct Answer
Option B is the correct answer.
Detailed Explanation
The lecture states that the centripetal force is F = mv²/r, which is the product of mass and the centripetal acceleration.
Hint
From Newton's second law, F = ma. If 'a' is centripetal acceleration, what is F?
