MCQ
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
- ✓Increases
- BDecreases
- CRemains the same
- DFluctuates
✓
Answer
Correct option: A.
Increases
a
(a) $R = mg\cos \theta - \frac{{m{v^2}}}{r}$
(a) $R = mg\cos \theta - \frac{{m{v^2}}}{r}$
when $ \theta$ decreases $\cos \theta $ increases i.e., $R$ increases.
