1.	When a bicycle is in motio, the force of friction exerted by the ground on the two wheels is such that it actsA. in the backward direction on the front wheel and in the forward direction on the rear wheelB. in the forward direction on the front wheel and in the backward direction on the rear wheelC. in the backward direction on both the front and the rear wheelsD. in the forward direction on both the front and the rear wheels
Answer» Correct Answer - C When the cycle is not pedaled but it is in motion (due to previous effort) the wheels move in the direction such that the centre of mass of the wheels moves forward. Rolling friction will act in the opposite direction to the relative motion of the centre of mass of the body with respect to the ground. Therefore the rolling friction will act in the backward directioin in both the wheels. The sliding friction will act in the forward direction of the rear wheel during pedaling.
