At what angle should a road be banked so that the vehicle may take a bend of radius 10 m travelling with a speed of `10m//s`
`( g=10 m//s^(2))`

A

`80^(@)`

B

`45^(@)`

C

`60^(@)`

D

`90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
` tan theta =(v^(2))/(rg)=(10xx10)/(10xx10)=1`
`theta =45^(@)`.
