A vehicle is moving with a velocity \( v \) on a curved road of width \( b \) and radius of curvature \( R \). For counteracting the centrifugal
\( \mathrm{P} \) force on the vehicle, the difference in elevation required in

W. between the outer and inner edges of the rod is
(1) \( v^{2} b / R g \)
(2) \( v b / R g \)
(3) \( v b^{2} / R g \)
(4) \( v b / R^{2} g \)
