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

Options

A. In the backward direction on the front wheel and in the forward direction on the front wheel and in the forward direction on the rear wheel when cycle is being pedalled
B. In the forward direction on the front wheel and in the backward direction on the rear wheel
C. In the backward direction on both the wheels when pedalling is stopped .
D. In the forward direction on both the wheels

Answer

a,c

Explanation

In cycling rear wheel moves by the force communicated to it by pedalling and front wheel moves on its own Hence while pedalling force exerted by rear wheel on ground makes force of friction act in forward direction Front wheel moving by itself experience force of friction in backward direction When pedalling is stopped both the weels moving themselves experience friction in backward direction .
