A 4 kg block A is placed onn 8 kg block B which rests on a smooth table,A just slips on when a force of 12 N is applied on A.What is the maximum horizontal force ,F required to make bothy A and B move together?

What acceleration will be produced in a body of mass 3 kg, when a force of 12 N is applied?

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?

A force of 3 kg weight is just sufficient to pull a block of 4 kg over a horizontal surface.What is the angle of friction?

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?

A uniform disc of radius R, is resting on a table on its rim. The coefficent of friction between disc and table is mu (show in the figure). Now the disc is pulled with a force F . What is the maximum value of F for which the disc rolls without slipping?

A conducting rod PQ of length 20 cm and resistance 0.1 Omega rests on two smooth parallel rqails of negligible resistance AA' and CC'. It can slide on the rails and the arrangement is positioned betwaeen the poles of a permanent magnet producing unifrom magnetic field B=0.4 T. The rails, the rod and the magneitc field are in the three mutually perpendicular directions as shown in the figure. if hte ends A and C of the rails are short cicuited, find the External force required to move the rod with uniform velocity v=10cm/s.

A horizontal force acts on a body placed on a smooth horizontal table . If the force applied is 10N,find the total work done when the displacement of body is 5m.​

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.

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?

A block of mass 1 kg is pushed up a surface inclined to horizontal at ang angle of 30^@ by a force of 10 N parallel to the inclined surface in the figure. shows . The coefficient of friction between bock and the incline is 0.1. If the block is pushed up by 10 m along the incline, calculate work done by applied force.
