A curved road of diameter 1.8 km is banked so that no friction is required at a speed of 30 m s − 1 . What is the banking angle?

Question

A curved road of diameter 1.8 km is banked so that no friction is required at a speed of 30 m s − 1 . What is the banking angle?, tan - 1 0 . 1, tan - 1 0 . 3, tan - 1 0 . 9, tan - 1 1 . 5

MARKS App · Accepted Answer

As, tan ⁡ θ = v 2 r g Where, θ = the angle of banking. ⇒ tan ⁡ θ = 30 × 30 10 × 0.9 × 10 3 = 0.1 ⇒ θ = tan - 1 ⁡ 0.1
