A car moves at a constant speed on a road as shown in figure. The normal force by the road on the car is `N_A and N_B` when it is at the points A and B respectively
.

A

`N_(A)= N_(B)`

B

`N_(A) gt N_(B)`

C

`N_(A) lt N_(B)`

D

Insufficient

Text Solution

Verified by Experts

The correct Answer is:
B

Normal reaction at highest point.
`mg-N=("mv"^(2))/(r)`
`N = mg-("mv"^(2))/(r)`
`r_(A)gt r_(B) implies N_(A) gt N_(B)`
