Question

Optimum speed for turning on a banked road is :

• A. $\sqrt{Rgtan\theta }$
• B. $\sqrt{Rgcot\theta }$
• C. $\sqrt{Rgsin\theta }$
• D. $\sqrt{Rgsec\theta }$

Answer 1

The correct option is A $\sqrt{Rgtan\theta }$

The correct option is A

The proper velocity or optimum v on a road banked by an angle θ with the horizontal is given by

$=\sqrt{Rgtan\theta }$

Where R is the radius of curvature of the road,

g is the acceleration due to gravity.
