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

Fluctuates

Text Solution

Verified by Experts

The correct Answer is:
A
`-R + mg cos theta = (mv^(2))/r rArr R = mg cos theta - (mv^(2))/r`

Since, `theta to` decreases : `cos theta` increase
[`cos theta` is decreasing function]
Hence, R increases.
