A particle is moving in a circular path. If its speed is halved, what will be the effect on its centripetal acceleration?
Q1. A particle is moving in a circular path. If its speed is halved, what will be the effect on its centripetal acceleration?
Answer: It will be reduced to 1/4
Explanation: Centripetal acceleration is proportional to v², so halving v will reduce a to 1/4, using a = v² / r.
