  • question_answer Two boys are riding their bicycle on the same concrete road. One has new tyres on his bicycle while the other has tyres that are old and used. Which of them is more likely to slip while moving through a patch of the road which has lubricating oil spilled over it?        

    Answer:

            The boy having the tyres which are old and used is more likely to slip because these tyres will experience less frictional force which is insufficient to move on the oily road.
