Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A stable well-designed racing car must have
A
low centre of gravity
B
narrow wheel base
C
long front
D
double exhausts
Explanation: 

Detailed explanation-1: -The correct answer is very low. The position of the center of gravity of an object affects its stability. The lower the center of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed.

Detailed explanation-2: -For a racing car, the CoG is located between the front and rear wheels and as close to the ground as physically possible. You know from traveling in a road car that when the driver brakes, the car dives down at the front.

Detailed explanation-3: -Racing cars have really low centres of gravity so that they can corner rapidly without turning over. Increasing the area of the base will also increase the stability of an object, the bigger the area the more stable the object.
