A car is negotiating a curved road of radius R. The road is banked at an angle `theta`. The coefficient of friction between the types of the car and the road is `mu_(s)`. The maximum safe velocity on this road is

`sqrt(gR(mu_(s)+tantheta)/(1-mu_(s)tantheta))`

`sqrt((gmu_(s)+tantheta)/(R1-mu_(s)tantheta))`

`sqrt((gmu_(s)+tantheta)/(R^(2)1-mu_(s)tantheta))`

`sqrt(gR^(2)(mu_(s)+tantheta)/(1-mu_(s)tantheta))`
