A cycle wheel of radius 0.4 m completes one revolution in one second then the acceleration of a point on the cycle wheel will be
0.8 m/s
0.4 m/s
1.6π2 m/s2
0.4π2 m/s2
Centripetal acceleration =4πnr=4π×(1)×0.4=1.6π
If a cycle wheel of radius 4 m completes one revolution in two seconds. Then acceleration of a point on the cycle wheel will be
