A motor-cyclist drives a motor cycle in a vertical circle. His minimum velocity at the highest point of the circle will be

Options

(a) √2Rg
(b) √3Rg
(c) √Rg
(d) 2Rg

Correct Answer:

√Rg

Explanation:

Frictional force = Centripetal force mg = mv² / R ⇒ v² = mgR / m ⇒ v² = Rg Therefore, minimum velocity v = √Rg
