To bring a body (of definite mass) into motion, it should have some acceleration. Hence, due to mass and acceleration it should have force in the direction of its motion. Now due to this force, an equal and opposite force should act on it according to newton's third law of motion. Therefore, due to two equal and opposite forces on the same body, it shouldn't move. Then, what is the reason behind that the body moves?

 

This reaction force acts on the external agency that is applying the force. So there is only  one extrnal force that is acting on the body, hence it will move. Always rememebr that action reaction forces donot act on teh same body.

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
