(a) NA = NB
(b) NA > NB
(c) NA < NB
(d) insufficient
Figure

Answer 1

Answer:

where is the figure keep it

Answer 2

A car moves at a constant speed on a road. The normal force by the road on the car NA and NB when it is at the points A and B is $N_{A}<\mathrm{N}_{B}$

Explanation:

• From the question figure it is obvious that $r_{B}>r_{A}$

• Proper reaction here is inverse proportional to the inertial force that acts on the vehicle, when turning on the curve line. Additionally, centrifugal force is inverse proportional to the circular path radius.

• Hence, we get:  

$N_{A}<N_{B}$

Centrifugal force:- A force that occurs from the inertia of the body that tends to act on a body traveling in a circular direction, and is guided away from the center around which the body travels.
