A uniform chain is placed at rest on a rough surface of base length l and height h on an irregular surface as shown in figure Then the minimum coefficient of friction between the chain and the surface must be equal to

A block of mass m is moving with a speed v on a horizontal rought surface and collides with a horizontal monted spring of spring constant k as shown in the figure .The coefficient of friction between the block and the floor is mu The maximum cobnpression of the spring is

A chain is placed on a rough table, partially hanging, as shown in the figure. The coefficient of static friction between the chain and the table is mu = 0.4. If the maximum possible length of the hanging part is x and the length of the chain is L, then what is the value of (L)/(x) ?

A chain is placed on a rough table, partially hanging, as shown in the figure. The coefficient of static friction between the chain and the table is mu = 0.4. If the maximum possible length of the hanging part is x and the length of the chain is L, then what is the value of (L)/(x) ?

A uniform ring placed on a rough horizontal surface is given a sharp impulse as shown in the figure-5.130. As a consequence, it acquires a linear velocity of 2m/s. If coefficient of friction between the ring and the horizontal surface is 0.4 :

A chain lies on a rough horizontal table. It starts skidding when one fourth of it’s length hangs over the edge of the table. The coefficient of static friction between the chain and the surface of the table 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
