Statement 1: While drawing a line on a paper by pencil, friction force acts on paper in the same direction along which line is drawn on the paper. Statement 2: Friction always opposes motion.

Assertion : The force of tension on a body always act away from the body. Reason: Friction force always opposes the motion of a body.

During rolling, the force of friction acts in the same direction as the direction of motion of the CM of the body.

Find the approximate area of an irregular lamina of which boundary line is drawn on the graph paper shown in Fig.

Statement - 1 : Maximum value of friction force between two surfaces is mu xx" normal reaction" . where mu = coefficient of friction between surfaces. Statement - 2 : Friction force between surfaces of two bodies is always less than or equal to externally applied force.

Statement I: A disc is allowed to roll purely on an inclined plane as shown in Fig. A force F parallel to the incline and passing through the centre of the disc acts which remains constant during the motion. It is possible that for certain values of F , the friction on the disc is acting along downward direction and for certain other values of F , the friction on the disc be acting along upward direction and there is no other possibility. Statement II: The friction (if acting) will be static and not kinetic in nature.
