Question
______ of friction is seen in the image.
- Advantage
- Disadvantage
- Either a or b
- None of the above
Hint:
The base of the sandals rubs off due to friction caused by walking. This is a disadvantage of friction which is called "wear and tear of soles of shoes".
The correct answer is: Disadvantage
Disadvantage of friction is seen in the image.
- The friction causes damage to the object when it is rubbed with rough surfaces.
- Walking causes friction between the sandals and the road.
- This will lead the sandals to rub off at their base (i.e. wearing and tearing of soles of shoes).
