The centre of gravity of a car is at a height `h` and the distance between its wheel is 2a. The car moves on a level curve of radius r with speed `v`. Let `N_(1) and N_(2)` be the normal reactions on the inner and outer wheels of the car. Then

A

`N_(1)gtN_(2)`

B

`N_(2)gtN_(1)`

C

`N_(1)=N_(2)`
