Question

If you want to go from one point to another point on a straight slippery path, then which of the following will be less risky?
(i) Walking with shoes with better grip
(ii) Riding bicycle
(Note that your shoes and the tyres of your bicycle are made of same material)

• A. Only (i)
• B. Only (ii)
• C. Both (i) and (ii) are equally useful
• D. Cannot be determined

Answer 1

The correct option is B Only (ii)

We know that there is a maximum limit of static friction and it is very less in the slippery road. Also, we know that rolling friction is lesser than the static friction. If a body rolls then it will need lesser static frictional force than if it try to slide. So riding bicycle is more convenient in the slippery road as it needs lesser static friction.
