Motion in A Plane

Question: A motor cyclist moving with a velocity of 72 km/hour on a flat road takes a turn on the road at a point where the radius of curvature of the road is 20 meters. The acceleration due to gravity is 10 m/sec2. In order to avoid skidding, he must not bend with respect to the vertical plane by an angle greater than


1) \[\theta = {\tan ^{ - 1}}6\]
2) \[\theta = {\tan ^{ - 1}}2\]
3) \[\theta = {\tan ^{ - 1}}25.92\]
4) \[\theta = {\tan ^{ - 1}}4\]
