A metallic wire with tension T and at temperature 30∘C vibrates with its fundamental frequency of 1‌kHz. The same wire with the same tension but at 10∘C temperature vibrates with a fundamental frequency of 1.001‌kHz. The coefficient of linear expansion of the wire is

2×10−4∕‌∘C
1.5×10−4∕‌∘C
1×10−4∕‌∘C
0.5×10−4∕‌∘C
