A body is moving in a circular path. If the radius is halved and the speed is doubled, what is the new centripetal force?
Q1. A body is moving in a circular path. If the radius is halved and the speed is doubled, what is the new centripetal force?
Answer: 8 times the original
Explanation: New F = m * (2v)² / (r/2) = 8 * mv²/r, so it becomes 8 times, using F = mv²/r.
