Keeping the angle of banking of the road constant, the maximum speed of the vehicles is to be increased by $10 %$ . The radius of curvature of the road will have to be changed from $20 m$ to

Options:

Answer:

Solution:

$\tan θ = \frac{v^{2}}{r g}$

$\Rightarrow r \propto v^{2}$
$\frac{r_{2}}{r_{1}} = {(\frac{v_{2}}{v_{1}})}^{2}$

or $\frac{r_{2}}{20} = {(\frac{1.1 v}{v})}^{2}$

$\Rightarrow r_{2} = 24.2 m$
