Mass of the blocks `A` and `B` is same and is equal to `m` each the interface between the blocks makes an angle of `37^(0)` with horizontal. Friction is absent every where the system is released from rest. Acceleration of `A` and `B` are `a_(A)` and `a_(B)` respectively. Let N be the normal force with which block `B` presses on the wall. Then, (Acceleration due to gravity

Two blocks A and B of equal mass m are connected through a massless string and arranged as shown in figure. The wedge is fixed on horizontal surface. Friction is absent everwhere. When the system is released from rest.

Two blocks A and B of equal mass m are connected through a massless string and arranged as shown in figure. The wedge is fixed on horizontal surface. Friction is absent everwhere. When the system is released from rest.

Figure shows two blocks each of mass m system is released from rest. If acceleration of blocks A and B at any instant (not initially) are a_(1) and a_(2) , respectively. Then

In the system shown in fig., m_(A)=4m , m_(B)=3m , and m_(c)=8m . Friction is absent everywhere. String is inextensible and light. If the system is released from rest, then Acceleration of Block B is

Block A is placed on block B, whose mass is greater than that of A. There is friction between the blocks, while the ground is smooth. A horizontal force P, increasing linearly with time, begins to act on A. The accelerations a_(1) and a_2 of A and B respectively are plotted against time (t). The correct graph is

A wooden block of mass M resting on a rough horizontal surface is pulled with a force T at an angle q to the horizontal. If m is coefficient of kinetic friction between the block and the surface, the acceleration of the block is

In fig the blocks A,B,and C of mass m each have acceleration a_(1),a_(2), and a_(3) , repectively. F_(1) and F_(2) are external force of magnitude 2mg and mg , respectively. Then
