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
