Question

A vehicle is moving with a velocity v on a curved road of width b and radius of curvature R. For counteracting the centrifugal force on the vehicle, the difference in elevation required in between the outer and inner edges of the rod is (A) v2 b / R g (B) v b / R g (C) v b2 / R g (D) v b / R2 g

Tardigrade Admin · Accepted Answer

tan θ=v2 / R g ⇒ (h/b)=v2 / R g ⇒ h=(v2 b/R g)

Q. A vehicle is moving with a velocity $v$ on a curved road of width $b$ and radius of curvature $R$ . For counteracting the centrifugal force on the vehicle, the difference in elevation required in between the outer and inner edges of the rod is

$v^{2} b / R g$

$v b / R g$

$v b^{2} / R g$

$v b / R^{2} g$

$tan θ = v^{2} / R g$
$\Rightarrow \frac{h}{b} = v^{2} / R g$
$\Rightarrow h = \frac{v ^{2} b}{R g}$
