Suppose the road gradient is G = 10%. What is the corresponding angle

1.	Suppose the road gradient is G = 10%. What is the corresponding angle (approximate value in radians)?(a) 5 rad(b) 0.1 rad(c) 1 rad(d) 10 radI have been asked this question during an online interview.This interesting question is from Vehicles and Powertrain in division Emission Control Methods, Electric & Conventional Vehicles of Automobile Engineering
Answer» Right choice is (B) 0.1 RAD Explanation: G = tan (α). For SMALL angles α, tan (α) = α. Hence α = 10% = 0.1 rad. The corresponding angle for road GRADIENT G = 10% is 0.1 rad.
