The length of a metal wire is $l_1$ when the tension in it is $T_1$ and is $l_2$ when the tension is $T_2$. The natural length of the wire is

Question

Accepted Answer

$\frac{l_1 T_2 - l_2 T_1}{T_2 - T_1}$

Answer

$\frac{l_1 + l_2}{2}$

Answer

$\sqrt{l_1 l_2}$

Answer

$\frac{l_1 T_2 + l_2 T_1}{T_1 + T_2}$
