Keeping the angle of banking, if the radius of curvature is made four times, the percentage increase in the maximum speed with which a vehicle can travel on a circular road is

`25%`

`50%`

`75%`

`100%`

Text Solution

Verified by Experts

The correct Answer is:

`tantheta=(v^(2))/(Rg)=(v_(2)^(2))/(4Rg)rArrv_(2)=2v_(1)`
`((v_(2))/(v_(1))-1)=1`
`%"increase"=100%`
