A car turns on a banked road of radius 300 m . If the coefficient of friction between the tyres and the road is 0.3 , then maximum speed of the car on the turn is [ Take , g=10 ~m / s ^2 . ]
Options
- A10 ~m / s
- B30 m/s
- C40 m/s
- D50 m/s
Correct answer
B. 30 m/s
Step-by-step solution
Given, r=300 ~m , =0.3 , g=10 ~m / s ^2 If v is the velocity of the vehicle while turning on the road, then array rlrl & & m v^2 r & m g array v r g v_ = r g = 0.3 300 10 =30 ~m / s
