In the figure shown, friction force between the bend and the light string is `(mg)/4`. Find the time in which the bead loose contact with the string after the system is released from rest.

In the fig shown below, friction force between the bead and the light string is (mg)/4 if t=sqrt((nl)/(7g)) where t is the time in which the bead loose contact with the string after the system is released from rest, find n

In the system shown in the figure , a bead of mass m can slide on the string. There is friction beween the bead and the string. Block B has mass equal to twice that of the bead. The system is released from rest with lenth l=18.75m of the string hanging below the bead. Assuming the pulley and string to be massless. Find the distance (in meter) moved by the block B before the bead slips out of the thread.

In the system shown in the fig., the bead of mass m can slide on the string. There is friction between the bead and the string. Block has mass equal to twice that of the bead. The system is released from rest with length l of the string hanging below the bead. Calculate the distance moved by the block before the bead slips out of the thread. Assume the string and pulley to be massless.

Wedge shown in the figure is fixed . System is released from rest (Neglect friction )

The friction coefficient between plank and floor is mu . The man applies, the maximum possible force on the string and the system remains at rest. Then

An arrangement of the masses and pulleys is shown in the figure. Strings connecting masses A and B with pulley are horizontal and all pulleys and strings are light. Friction coefficient between the surface and the block B is 0.2 and between block A and B is 0.7 . The system is released from rest. (use g=10m//s^(2))
