Vedclass · Answer

(D) The direction of the frictional force depends on the state of motion of the bicycle.$1$. When pedalling: The rear wheel is driven by the chain,pushing the ground backward,so the ground exerts a forward frictional force on the rear wheel. The front wheel is rolling freely,so it experiences a backward frictional force to oppose its motion.$2$. When coasting (pedalling stopped): Both wheels are rolling freely. In this case,both wheels experience a backward frictional force from the ground to oppose their forward motion.Since the question asks about the general motion of a bicycle,it covers both scenarios depending on whether the rider is pedalling or coasting. Therefore,both $(a)$ and $(c)$ are valid descriptions of the frictional force acting on the wheels under different conditions.

When a bicycle is in motion,the force of friction exerted by the ground on the two wheels is such that it acts
