A wire of resistance R is stretched to thrice its original length keeping the volume constant. Calculate its new resistance.

Explanation

To find the new resistance of a wire that has been stretched to thrice its original length while keeping the volume constant, we can follow these steps:

### Step 1: Understand the relationship between resistance, resistivity, length, and area
The resistance \( R \) of a wire is given by the formula:
\[ R = \frac{\rho L}{A} \]
where:
