A body is moving in a circular path. If its linear velocity is doubled, what happens to its centripetal acceleration?
Q1. A body is moving in a circular path. If its linear velocity is doubled, what happens to its centripetal acceleration?
Answer: It is quadrupled
Explanation: New a_c = (2v)² / r = 4 * (v² / r) = 4 * a_c, using the formula a_c = v² / r.
