Problem

A motor cyclist moving with a velocity of 72 km/hr 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 \text{ m/s}^2

. 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
