Keeping The Banking Angle Same To Increase The Maximum Speed With Which A Car Can Travel On A Curved Road By 10% The Radius Of Curvature Of Road Has To Be Changed From 20m To 16m

Keeping the banking angle same to increase the maximum speed with which a car can travel on a curved road by 10% the … 18m (c)…


Correct Option (c) 24.25m 


tan θ = v2/r g ⇒ r ∝ v2

(if θ is constant)

r2/r1 = (v2/v1)2 = (1.1v/v)2 = 1.21

⇒ r2 = 1.21 × r1 = 1.21 × 20

⇒ 24.2 m
