Fig.
shows two blocks A and B having masses 1 kg and 2 kg respectively. A force of 5 N is applied on A. Coefficient of friction between A and B is 0.2 and that of between B and horizontal surface is zero. Find acceleration of A and B.

Two bodies A and B of masses 5 kg and 10 kg in contact with each other rest on a table against a rigid wall (Fig. 5.21). The coefficient of friction between the bodies and the table is 0.15. A force of 200 N is applied horizontally to A. What are :- the reaction of the partition.

Three blocks A,B and C weighing 1 kg, 8 kg, and 27 kg respectively are connected a shown in the figure with inextensible string and are moving on smooth surface.If F=36 N,then T is : .

Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string, a horizontal force F = 600 N is applied to:- A what is the tension in the string?

m_1 and m_2 are the masses of two bodies. When a force of 5 N is applied on each body, m_1 gets an acceleration of 10 m//s^2 and m_2, 20 m//s^2. If the two bodies are tied together and the same force is applied, find the acceleration of the combined system.

Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string, a horizontal force F = 600 N is applied to:-B along the direction of string. What is the tension in the string in each case?

Figure 5.18 shows a man standing stationary with respect to a horizontal conveyor belt that is accelerating with 1 m s^-2 . What is the net force on the man? If the coefficient of static friction between the man’s shoes and the belt is 0.2, up to what acceleration of the belt can the man continue to be stationary relative to the belt ? (Mass of the man = 65 kg.)

A force of 100 N is able rp produce an acceleration 8 m s^-2 in body of mass 10 kg. finf the value of force of friction.

Two bodies of masses 10kg and 20 kg respecively kept on a smooth, horizontal surface are tied to the ends of a lght string. A horizontal force F= 600 N is applied to (i) A (ii) B along the direction of string. What is the tension in the string in each case?
