What will be resistivity of a copper wire B compared to another copper wire A of triple its length and double its diameter ?

Explanation

To determine the resistivity of copper wire B compared to copper wire A, we need to analyze the properties of resistivity and how they relate to the materials involved.

### Step-by-Step Solution:

1. **Understand the Concept of Resistivity**:
- Resistivity (ρ) is a property of a material that quantifies how strongly it resists the flow of electric current. It is independent of the dimensions of the wire (length and diameter) and depends only on the material and temperature.

2. **Identify the Materials**:
...
