A turn has a radius of `10m` if a vehicle goes round it at an average speed of `18km//h` , what should be the proper angle of banking?

A

`theta=tan^(-1)((1)/(3))`

B

`theta=tan^(-1)((1)/(8))`

C

`theta=tan^(-1)(1)`

D

`theta=tan^(-1)((1)/(4))`

Text Solution

Verified by Experts

The correct Answer is:
D
`v=(18xx5)/(18)=m//s`
`tantheta=(v^(2))/(Rg)=((5)^(2))/(10xx10)=(1)/(4)`
:. `theta=tan^(-1)((1)/(4))`
