The pilot of an aircraft, who is not tied to his seat, can loop a verticle circle in air without falling out at the top of the loop . What is the minimum speed required so that he can successfully negotitate a loop of radius 4 km ? `(g=10 m//s^(2))`

A

`100 m//s`

B

`200 m//s`

C

`300 m//s`

D

`400 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`v=sqrt(rg)`
`=sqrt(40000xx10)=sqrt(4xx10^(4))=2xx10^(2)`
`=200 m//s`
