25% of a uniform chain hangs from the edge of a horizontal table top. If the chain is on the verge of sliding,the coefficient of static friction between the chain and horizontal table is

A chain AB of length equal to the quarter of a circle of radius R is placed on a smooth hemisphere as shown in figure -3.66. When it is released, it starts falling. Find the velocity of the chain when it falls of the end B from the hemisphere.

A uniform chain of length l and mass m lies on a smooth table. A very small part of this chain hangs from the table. It begins to fall under the weight of hanging part. Find the velocity of chain when the length of hanging part becomes y.

The system shown is just on the verge of slipping. The coefficient of static friction between the block and the table top is :

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 chain of length L and mass M is held on a frictionless table with (1//n)th of its length hanging over the edge. When the chain is released, find the velocity of chain while leaving the table.
