A) \[\frac{m{{v}^{2}}}{r}\ge \mu mg\]
B) \[\frac{m{{v}^{2}}}{r}\le \mu mg\]
C) \[\frac{m{{v}^{2}}}{r}=\mu mg\]
D) \[\frac{v}{r}=\mu g\]
Correct Answer: B
Solution :
When a vehicle takes a turn on a circular path it requires centripetal force. If friction provides this centripetal force then vehicle can move in circular path safely. ie. Friction force >. Required centripetal force\[\mu mg\ge \frac{m{{v}^{2}}}{r}\]You need to login to perform this action.
