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

Consider a bicycle first. Pedaling the bicycle merely
rotates the back wheel in clockwise sense. The velocity of
point of contact is therefore backwards. Hence, friction
must act forward on the rear wheel.

This frictional force causes a translational acceleration
of the entire bicycle, including the front wheel. The
velocity of point of contact tends to develop in the
forward direction. So friction acts in the backward
direction.

Similar reasoning apply to a car, for the engine merely
rotates the backwheel

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

(a) because when cycle is paddled its rear wheel moves in
forward direction but the point where wheel touches the
ground is in backward direction so friction will be in
forward direction in rear wheel but as the front wheel is
not getting any torque so it will be stationary and the
force that rotates it is only frictional force from ground.
so the friction will be in backward direction in front wheel
as only then front wheel will start rotating in the
rotational direction of rear wheal.

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

option a) when we are pedaling the cycle

option c) when not being pedaled

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

Friction force act in forward direction because friction act in opposite to that direction of motion of wheel

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

A and c both are correct because there can be two cases 1 when the cycle is being paddled 2.when not paddled

The options are wrong here... please check options "c" n "d"
n make the correction.

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

ans(d)
since any friction force which is acting upon the body will be opposite to the flow of object...so the same force is exerted on front and rear wheels of the cycle
