A persong whants to drive on the verical surface of a large cylindrical wooden wll commonly know as death well in a circus. The radius of well is R and the coefficient of friction between the tyres of the motorcycle and the wall of the well is `mu_(s)`.The minimum speed, the motorcyclist must have in order to prevent slipping should be

A

`sqrt(((Rg)/(mu_(s))))`

B

`sqrt(((mu_(s))/(Rg)))`

C

`sqrt(((mu_(s)g)/(R)))`

D

`sqrt(((R)/(mu_(s)g)))`

Text Solution
