Keeping the banking angle same to increase the maximum speed with which a vehicle can travel on a curved road, by 10% the radius of curvature of the road has to be changed from 20 m to-

A

16 m

B

18 m

C

24.2 m

D

30.5 m

Answer

24.2 m

Explanation

Solution

tan q = v2rg\frac{v^{2}}{rg}

If q is constant then r µ v2 r′r\frac{r'}{r}= (1.1vv)2\left( \frac{1.1v}{v} \right)^{2}
