MHT CET 2025 23rd April Morning Shift | Circular Motion Question 7 | Physics

Radius of curved road is ' $R$ ', width of road is ' $b$ '. The outer edge of road is raised by ' $h$ ' with respect to inner edge so that a car with velocity ' $V$ ' can pass safe over it, then value of ' $h$ ' is ( $\mathrm{g}=$ acceleration due to gravity)

$\frac{\mathrm{V}^2 \mathrm{~b}}{\mathrm{Rg}}$

$\frac{\mathrm{V}}{\mathrm{Rgb}}$

$\frac{V^2 R}{g}$

$\frac{V^2 b}{g}$
