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

remain the same

D

fluctuates

Text Solution

Verified by Experts

The correct Answer is:
A
`R=mgcostheta-(mv^(2))/(r)`
When `theta` decreases, `coshteta` increases i.e., `R` increases.
