For the given figure the acceleration of 1 kg block if string is massless and mass of pulley is 2 kg and diameter of pulley is 0.2 m :-

The force exerted by the ideal string on the ideal pulley P shown in the figure is

A block of mass m is attached with a massless spring of force constant k. The block is placed over a rough inclined surface for which the coefficient of friction is mu=(3)/(4) . The minimum value of M required to move the block up the plane is (Neglect mass of string, mass of pulley and friction in pulley)

A block of mass m is attached with a massless spring of force constant K. the block is placed over a rough inclined surface for which the coefficient of friction is mu =3/4 find the minimum value of M required to move the block up the place. (Neglect mass of string and pulley. Ignore friction in pulley). .

A uniform cubical block of mass M is attached to a pulley. One end of a string, passing over the pulley is fixed to a light pole while is fixed on the bigger block and its another end is attached to a block of mass m as shown in figure. The maximum value of the mass m so that the block does not topple is : (string and pulley are ideal)

Under the condition shown in figure. Find out the minimum value of horizontal force F_(2) on pulley, which can be applied without causing any motion (assume pulley & strings are light)

PQR is a wedge fixed to the floor. Two blocks A & B of equal mass m=1kg is placed on either side of wedge connected through a string passing over the pulley P . Initially PB=PA . Another block C of mass m=1kg moving with a velocity 10m//s collides inelasically with A . All the surfaces are smooth and pulley & string are massless. ( a ) What should be the minimum length of the string AB so that block A does not hit the pulley ? ( b ) What is the loss in meechanical energy from the instant C hits A to the instant when B starts moving upward ? ( g=10m//s^(2) )

In the system shown in the fig. there is no friction and string is light. Mass of movable pulley P_(2) "is" M_(2) . If pulley P_(1) is massless, what should be value of applied force F to keep the system in equilibrium?
