A uniform chain of mass m and length l is at the verge of sliding under the effect of gravity of the hanging part. Find the a. coefficient of friction, between chain and table. b. work done by friction and gravity till the chain leaves the table if the hanging part is pulled gently and released. c. speed of the chain at the time of leaving the table in part (b) . d. work done by the external force acting at the end A of the chain in slowly pulling the chain completely onto the table.

A rope of length 30cm is on a horizontal table with maximum length hanging from edge A of the table. The coefficient of friction between the rope and table is 0.5 . The distance of centre of mass of the rope from A is

A uniform rope of total length l is at rest on a table with fraction f of its length hanging (see figure). If the coefficient of friction between the table and the chain is mu then

A uniform chain of length l is placed on a rough table, with length l//3 hanging over the edge. If the chain just begins to slide off the table by itself from this portion, the coefficient of friction between the chain and the table is 1/K. Then find the value of K.

A rope of length L and mass M is being pulled on a rought horizontal floor by a contact horizontal force F = m g . The force is acting at one end of the rope in the same direction as the length of the rop. The coefficient of kinetic friction between rope and floor is 1//2 . Then the tension at the midpoint of the rop is
