A) The inner wheel which leaves the ground first
B) The outer wheel which leaves the ground first
C) Both the wheel leave the ground simultaneously
D) Either wheel will leave the ground first
Correct Answer: A
Solution :
[a] The car over turn, when reaction on inner wheel of car is zero, i.e., first the inner wheel of car leaves the ground (where G is C.G of car, h is height of C.G from the ground, \[{{\text{f}}_{1}}\] & \[{{\text{f}}_{1}}\] are frictional force exerted by ground on inner & outer wheel respectively).
The max. Speed for no over-turning is \[{{V}_{\max }}=\sqrt{\frac{gra}{h}}\] Where r is radius of the path followed by car for turn & 2a is distance between two wheels of car (i.e., AB)
