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

A

increases

B

decreases

C

remains the same

D

fluctutates

Text Solution

Verified by Experts

The correct Answer is:
A
`mg cos theta-N=(mv^(2))/(R )`
`N=mg cos theta-(mv^(2))/(R )`
As `theta` decrease, cos `theta` increase. Hence,`N` increase.
