Q.18 A motorcycle moving with a velocity of 72 km h –1
on a flat road takes a turn on the road at a point
where the radius of curvature of the road is 20 m.
The acceleration due to gravity is 10 ms –2 . In
order to avoid skidding, he must not bent with
respect to the vertical plane by an angle greater
than -
(1) θ = tan –1 (2) (2) θ = tan –1 (6)
(3) θ = tan –1 (4) (4) θ = tan –1 (25.92)
