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

a) In the backward direction on the front wheel and in the
forward direction on the rear wheel.
(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 front and rear
wheels.
(d) In the backward direction on both the front and rear
wheels.

Answer Posted / bhuwan kalra

(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.
