If b is the wheel track of a vehicle and h is the height of centre of gravity above road surface, then to avoid overturning and lateral skidding on a horizontal curve, the centrifugal ratio should always be

A Less than $$\frac{{\text{b}}}{{2{\text{h}}}}$$ and greater than co-efficient of lateral friction
B Less than $$\frac{{\text{b}}}{{2{\text{h}}}}$$ and also less than co-efficient of lateral friction
C Greater than $$\frac{{\text{b}}}{{2{\text{h}}}}$$ and less than co-efficient of lateral friction
D Greater than $$\frac{{\text{b}}}{{2{\text{h}}}}$$ and also greater than coefficient of lateral friction

Correct Answer: Less than $$\frac{{\text{b}}}{{2{\text{h}}}}$$ and also less than co-efficient of lateral friction
