Question

While walking on ice, one should take small steps to avoid slipping. This is because small steps ensure
(a) larger friction (b) smaller friction

(c) larger normal force (c) smaller normal force

Answer 1

First Read the Reason,

Let the magnitude of the Fore be F.

Now, If it is making an angle α with the vertical and this angle is continuously decreasing and becomes θ, then the vertical component will be FCosθ and Horizontal Component will be FSinθ.

Since, F Sinθ will be balanced by the Frictional Force.

Mathematically, Frictional Farce = F Sinθ

Now, this may be possible that the angle will continuously to decrease. Now, If the angle of sine is decreasing then the value will also decrease.

∴ Frictional force will decrease.

Now, After Reading that.

We came to know that as the angle decreases the Horizontal component and the Friction both decreases.  

Now, We used to walk on the Ice slowly so that the Force between the legs and ice will be small which will ensure the smaller friction and we can move on it Slowly.  

Hence, Option (b). is correct. Friction will be less.

Hope it helps.

Answer 2

Hi , friend !!

while walking on ice one should take a small step to avoid slipping this is because the a small step ensure that Friction is smaller .

so that the people who walking on ice doesn't sleep.

hence option number B is correct

hope it help you !!!

thanks !!
