Question

John wants to go to school on his bicycle. The grooves of his bicycle's tyres are worn out due to heavy use. Suggest the suitable path that he should take to avoid slipping.

• A.
• B.
• C.

Answer 1

The correct option is A

• Friction is maximum between the bicycle’s tyres and the dry road due to roughness and irregularities of the road. The large friction provides sufficient grip between the tyres and the road.
• The wet road and the muddy road don’t provide the sufficient friction to avoid slipping due to less roughness.
