Question

While walking on ice one should take small steps to avoid slipping. This is because smaller steps ensure:

• A. larger friction
• B. smaller friction
• C. larger normal force
• D. smaller normal force

Answer 1

Answer: (C)

larger normal force

$Fcos\theta =N$ and $f=Fsin\theta$
As $\theta$ increases , N decreases. Thus the maximum value of frictional force which is $\mu N$ decreases and slipping takes place if the limiting value of the frictional force is achieved.
