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

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

A block on table shown in is just on the edge of slipping Find the coefficient of static friction between the blocks and table .

A uniform chain of length l is placed on rough table with length l//n (where n gt 1 ) , hanging over the edge. If the chain just begins to slide off the table by itself from this position, the coefficient of friction between the chain and the table is

A chain is lying on a rough table with a fraction 1/n of its length hanging down from the edge of the table. if it is just on the point of sliding down from the table, then the coefficient of friction between the table and the chain is -

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 rough inclined plane is inclined at 30° to the horizontal as shown in the figure. A uniform chain of length L is partly on the inclined plane and partly hanging from the top of the incline. If the coefficient of friction between chain and inclined plane is H, the maximum length of the hanging part to prevent the chain from falling vertically is 30°

A small coin is placed on a flat horizontal turn table. The turn table is observed to make three revolutions in 3.14 sec . What is the coefficient of static friction between the coin and turn table if the coin is observed to slide off the turn table when it is greater than 10cm from the centre of turn table .
