Mr. A, B and C are trying to put a heavy piston into a cylinder at a mechanical workshop in railway yard. If they apply forces `F_(1), F_(2) and F_(3)` respectively on ropes then for which set of forces at that instant, they will be able to perform the said job?

A

`sqrt(3)F_(1)=F_(2)+2F_(3)`

B

`2F_(1)=F_(2)+F_(3)`

C

`2F_(2)=sqrt(3)F_(1)-(F_(3))/(2)`

D

`F_(3)=2F_(1)-sqrt(3)F_(2)`
