A) increases
B) decreases
C) remains the same
D) fluctuates erratically
Correct Answer: A
Solution :
Reaction of normal force on the motor cyclist \[Mg\cos \theta -N=\frac{m{{v}^{2}}}{R}\] or \[N=mg\cos \theta -\frac{M{{v}^{2}}}{R}\] As the motor cyclist moves upward on the bridge, \[\theta \] decreases and therefore, \[N\] increases and becomes maximum at the highest point.You need to login to perform this action.
