A wire of length `L` metres, made of a material of specific gravity 8 is floating horizontally on the surface of water. If it is not wet by water, the maximum diameter of the wire (in mm) upto which it can continue to float is (surface tension of water is `T=70xx10^(-3)Nm^(-1)`)

A

1.5

B

1.1

C

0.75

D

0.55

Text Solution

Verified by Experts

The correct Answer is:
A
`d=sqrt((8T)/(pirhog))because (2lxxT=mg rArr 2lT=rho xxpir^(2)lg)`
