A metalic wire of diameter `d` is lying horizontally o the surface of water. The maximum length of wire so that is may not sink will be

`sqrt((2T)/(pidg))`

`sqrt((2Tg)/(pid))`

`sqrt((2pid)/(Tg))`

any length

Text Solution

Verified by Experts

The correct Answer is:

`mg=2Tl rArr pir^(2) l rho g = 2Tl rArr pir^(2) rho g = 2T`
the expression is independent of length
