A particle is moving in a circular path of radius 1 m with a constant speed. If its centripetal acceleration is 4 m/s², what is its speed?
Q1. A particle is moving in a circular path of radius 1 m with a constant speed. If its centripetal acceleration is 4 m/s², what is its speed?
Answer: 2 m/s
Explanation: Centripetal acceleration (a_c) is given by v²/r. So, v = √(a_c * r) = √(4 * 1) = 2 m/s.
