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

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.

Statement- 1: Motion of a charged particle under the action of a magnetic field alone is always with constant speed. Statement- 2 : The direction of magnetic force is always perpendicular to the direction of motion of the charged particle.(1) Both Statements are true (2) Both Statements are false (3) Statement-1is true but Statement-2is false (4) Statement-1is false but Statement-2is true
