A cyslist goes round a circular path of length 4000 m in 20 second. Calculate the angle through which he bends from vertical in order to maintain the balance

A

`sin^(-1)(0.64)`

B

`tan^(-1)(0.64)`

C

`cos^(-1) (0.64)`

D

None of these

Text Solution

Verified by Experts

(a) `400=2pir`
`therefore" " tantheta=(v^(2))/(rg)=((400/20)/(400/(2pi)))^(2)g`
`therefore" " tantheta=(400x2pi)/(400g)=(6.28)/(9.8)=0.64`
`therefore" " theta=tan^(-1)(0.64)`
