The banking angle for a curved road of radius 490 m for a vehicle moving at 35 `ms^(-1)` is

A

`tan^(-1) ( 0.25 )`

B

` tan ^(-1) ( 0.35 )`

C

`tan^(-1) (1)`

D

`tan^(-1) ( 0.65 )`

Text Solution

Verified by Experts

The correct Answer is:
A
Here `, v= 35 ms^(-1) , r- 490 m`
` therefore tan theta = (v^2)/(rg ) = ((35 )^2)/( 490 xx 9.8 ) = 0.25`
` or theta = tan^(-1) ( 0.25 )`
