A particle is moving in a circular path. If its speed is doubled, what will be the effect on its centripetal acceleration?
Q1. A particle is moving in a circular path. If its speed is doubled, what will be the effect on its centripetal acceleration?
Answer: It will be quadrupled
Explanation: Centripetal acceleration is proportional to v², so doubling v will quadruple a, using a = v² / r.
