A fixed wedge ABC is in the shape of an equilateral triangle of side `l`. Initially, a chain of length `2l` and mass m rests on the wedge as shown. The chain is slowly being pulled down by the application of a force F as shown. Work done by gravity till the time, the chain leaves thw wedge will be:

A constant horizontal force (F) is applied at the vertex A of an equilateral triangular wedge ABC of mass M and side length AB=BC=CA= l_(1) placed on a rough horizontal surface as shown in the figure. Even after the application of force F the wedge remains stationary. Calculate the torque of normal reaction acting between the wedge and the floor about the vertex B.

A uniform chain of length 2m is kept on a table such that a length of 60 cm hangs freely from the edge of the table . The total mass of the chain is 4 kg What is the work done in pulling the entire the chain the on the table ?

A uniform chain of length L and mass M is tying on a smoth table and one third of its length is banging vertically down table the edge of the table if g is acceleration the to gravity , the work required to pull the hanging part on the table is

A block of mass m is at rest on wedge as shown in figure. Let N be the normal reaction between two and f the force of friction, then choose the wrong option.

A man places a chain (of mass m and length l ) on a table slowly. Initially, the lower end of the chain just touches the table. The main brings down the chain by length l//2 . Work done by the man in this process is
