A motorcycle is going on an overbridge of radius $R$. The driver maintains a constant speed. As the motorcycle is ascending on the overbridge, the normal force on it

AIncreases

BDecreases

CRemains the same

DFluctuates

Solution

(a) $R = mg\cos \theta – \frac{{m{v^2}}}{r}$
when $ \theta$ decreases $\cos \theta $ increases i.e., $R$ increases.
