Q. No.Copper of fixed volume \(V\) is drawn into a wire of length \(l.\) When this wire is subjected to a constant force \(F,\) the extension produced in the wire is \(\Delta l.\) Which of the following graphs is a straight line?
1. \(\Delta l ~\text{vs}~\frac{1}{l}\)
2. \(\Delta l ~\text{vs}~l^2\)
3. \(\Delta l ~\text{vs}~\frac{1}{l^2}\)
4. \(\Delta l ~\text{vs}~l\)

| 1. | \(\frac{5 q}{\left(7 \mathrm{sp}^2\right)} \) | 2. | \(\frac{7 q}{\left(5 sp^2\right)} \) |
| 3. | \(\frac{2 q}{(5 s p)} \) | 4. | \(\frac{7 q}{(5 s p)}\) |
