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

Step-by-step solution

Reaction of normal force on the motor cyclist M g -N= m v^2 R or N=M g - M v^2 R As the motor cyclist moves upward on the bridge, decreases and therefore, N increases and becomes maximum at the highest point.
