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

A
NA=NB
B
NA⥂>6muNB
C
NA⥂<6muNB
D
All possibilities are there
Answer
NA⥂<6muNB
Explanation
Solution
From the formula N=mg−rmv2 ∴ N ∝ r
As rA < rB ∴ NA<NB
