A moter cyclist loops a vertical circular loop of diameter 18 m, without droping down , even at the highest point of the loop . What should be his minimum speed at the lowest point of the loop ?
A
`10 m//s`
B
`16 m//s`
C
`21 m//s`
D
`30m//s`
Text Solution
Verified by Experts
The correct Answer is:
C
`V= sqrt(5 gl) = sqrt(5xx 9.8 xx9) = 21 m//s`
