Q: When a bicycle is driven by constant acceleration then the friction force on the rear wheel is –
  • A. zero
  • B. in the forward direction
  • C. backward direction
  • D. all these
Correct Answer: Option B - When a bicycle is driven by constant acceleration then the friction force on the rear wheel is in the forward direction. When a bicycle is in motion the force of friction exerted by the ground on the two wheels (front and rear) is F₁ and F₂ respectively. Then F₁ is in backward direction and F₂ is in forward direction
B. When a bicycle is driven by constant acceleration then the friction force on the rear wheel is in the forward direction. When a bicycle is in motion the force of friction exerted by the ground on the two wheels (front and rear) is F₁ and F₂ respectively. Then F₁ is in backward direction and F₂ is in forward direction

Explanations:

When a bicycle is driven by constant acceleration then the friction force on the rear wheel is in the forward direction. When a bicycle is in motion the force of friction exerted by the ground on the two wheels (front and rear) is F₁ and F₂ respectively. Then F₁ is in backward direction and F₂ is in forward direction
