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)`)

Options

A. 1.5
B. 1.1
C. 0.75
D. 0.55

Explanation

To solve the problem, we need to determine the maximum diameter of a wire made of a material with a specific gravity of 8 that can float on water without being wet by it. We will use the concepts of surface tension and buoyancy.

### Step-by-Step Solution:

1. **Understanding the Forces Acting on the Wire:**
The wire is floating horizontally on the surface of the water. The only force acting upward to balance the weight of the wire is the force due to surface tension. Since the wire is not wet, we can assume that it is floating due to the surface tension acting on both sides of the wire.

2. **Calculating the Force Due to Surface Tension:**
