Question

A road is banked at an angle of 30 ∘ to the horizontal for negotiating a curve of radius 1 0 3 m . At what velocity will a car experience no friction while negotiating the curve? Take g = 10 ms − 2, 54 km/hr, 72 km/hr, 36 km/hr, 18 km/hr

MARKS App · Accepted Answer

For negotiating curve without friction tan θ = V 2 rg V = rg tan θ = 10 m/s = 36 km/hr
