A) Nature of the material
B) Radius of the wire
C) Length of the wire
D) None of the above
Correct Answer: D
Solution :
\[K=\frac{YA}{L}=\frac{Y\times \pi {{r}^{2}}}{L}\Rightarrow K\propto \frac{Y{{r}^{2}}}{L}\] i.e. force constant of a wire depends on young's modules (nature of the material), radius of the wire and length of the wire.
