Answer the following :
In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move :
How can this force be increased ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : Which force is being applied here ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : When can we say that work is done by the applied force ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : If the block moves forward we can say that it has been displaced . due to the displacement , we sat that the force has done some work . can we measure this work ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : What will happen on applying more force ?:

A block of mas M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is theta the block just begins to slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane ?

Wooden block of weight W_(1) is kept on a horizontal surface. A pan is attached to a string which passed over the pulley and other end of the string is attached to block. The weight F_(1) is placed in the pan. If the block still remains stationary then

Solve the following questions : When certain weight is tied through pulley , the block gets displaced through displacement of 50cm .the work done on the block is 2500 erg then , how much force is applied on the block by weight ?

Given in figure are two blocks A and B of weight 20N and 100N, respectively. These are being pressed against a wall by a force F as shown. If the coefficient of friction between the blocks is 0.1 and between block B and the wall is 0.15, the frictional force applied by the wall on block B is:

Three blocks with masses m, 2m and 3m, are connected by strings, as shown in the figure. After an upward fforce F is applied on block m, the masses move upward at constant speed v. What is the net force on the block of mass 2m? (g is the acceleration due to gravity)
