One end of uniform wire of length L and ...

One end of uniform wire of length `L` and of weight `W` is attached rigidly to a point in the roof and a weight `W_(1)` is suspended from its lower end. If `s` is the area of cross section of the wire, the stress in the wire at a height (`3L//4`) from its lower end is

A

`(( w_(1) + (3w//4) )/( S) )`

B

`( ( w+ ( 3w_(1) //4) )/( S) )`

C

`( w_(1) + w)/( 4)`

D
