Verified by Experts
The correct answer is:
B

Reaction on inner wheel \(r_1 = \frac{1}{2} m \left| g \cdot v^{-1} h \right|\)

Reaction on outer wheel \(R_c = \frac{1}{2} M \left| g + \frac{v^2}{r \alpha} \right|\)

where, r = radius of circular path, 2 a = distance between two wheels and h = height of centre of gravity of car.
