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

`-(((sqrt(3)+1)mgl)/(2))`

B

A fixed wedge ABC is in shape of equilateral triangle of side l. Initially , achain 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 the 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.
