Q. 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 forces on it is :

Work, Energy and Power Report Error

Solution:

As motor cycle is ascending on the overbridge, the component of weight along radial dirction increases so the normal force also increases.
