A) 60
B) 30
C) 15
D) 25
Correct Answer: B
Solution :
To move a body on a circular path, centripetal force is necessary. In this question, there is an agent, friction that will provide the required centripetal force to the car. Using the relation \[\frac{m{{v}^{2}}}{r}=\mu R,R=mg\] \[\frac{m{{v}^{2}}}{r}=\mu mg\] or \[{{v}^{2}}=\mu rg\] or \[{{v}^{2}}=0.6\times 150\times 10\] or \[v=30\,m/s\]You need to login to perform this action.
