in the given figure a ring of mass m is kept on a horizontal surface while a body of equal mass m si attached through string, which is wounded on the ring. When the system is released the ring rolls without slipping. consider the following statement and choose the correct options. (i). Acceleration of centre of mass of ring is (2g)/(3) (ii). acceleration of hanging particle is (4g)/(3) (iii). Frictional force (on the ring) acts in backward direction. (iv) . Frictional force (on the ring) acts in backward direction.

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.

A : When a man is walking on a rough road, that work done by frictiona force is zero. R : Frictional force acts in the direction of the motion of the man in this case.

"When a person walks on a rough surface the frictional force exerted by the surface on the person is opposite to the direction of his motion". Is it true or false ?

Assertion :- When a man climbs the rope friction force acts in downward direction. Reason :- Friction force opposes relative motion ot tendency of relative motion between two contact surfaces.

Assertion : A sphere is placed in pure rolling condition over a rough inclined surface.Then, force of friction will act in downward direction Reason : Angular acceleration (actually retardation) due to friction is anti-clockwise.

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.

Consider a block of mass m that slides down the different inclined planes having same base legth L and same coefficient of friction. STATEMENT-1 Work done by force of friction will be same for the motion of the two inclined planes. STATEMENT-2 Frictional force is a conservation force.

When a person walks on a rough surface, the frictional force exerted by surface on the person is opposite to the direction of his motion. It is the force exerted by the road on the person that causes the motion.

(a) How does a centripetal force differ from a centrifugal force with reference to the direction in which they act? (b) Is centrifugal force the force of reaction of the centripetal force? ( c) compare the magnitudes of centripetal and centrifugal force.
