  • decreases

  •  remains the same

  • fluctuates.

Solution

The normal force on the motorcycle , \[\text{N = mg}\cos\theta - \frac{\text{mv}^2}{R}\]

As the motorcycle is ascending on the overbridge, θ decreases (from \[\frac{\pi}{2}\] to 0).

So, normal force increases with decrease in θ.

  Is there an error in this question or solution?
