In a well of death, motor cycle rides round the inner wall of a hollow cylindrical chamber. If the radius of the cylindrical chamber is 8 m . What would be minimum speed of the rider to prevent him from sliding down? `(g=10 m//s^(2), mu =0.2)`

A

`10 m//s`

B

`20 m//s`

C

`30 m//s`

D

`40 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`v=sqrt((rg)/(mu))=(8xx100)/(2)=sqrt(400)=20 m//s`
