Question

A motorcycle 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 m. The acceleration due to gravity is 10 m ⁄ s² . In order to avoid skidding, he must not bent with respect to the vertical plane by an angle greater than : 

(a) θ = tan⁻¹ (2) 

(b) θ = tan⁻¹ (6) 

(c) θ = tan⁻¹ (4)

(4) (d) θ = tan^-1 (25.92)

Answer 1

Correct option  (a) θ = tan⁻¹ (2)

Explanation:

Using the formula for motor cycle not ot to skid
