Question

The length of a metal wire is l₁, when the tension in it is T₁, and is l₂ when the tension is T₂. The natural length of wire is

• A. \(\frac{l_1+l_2}{2}\)
• B. \(\sqrt{l_1l_2}\)
• C. \(\frac{l_1T_2-l_2T_1}{T_2-T_1}\)
• D. \(\frac{l_1T_2+l_2T_1}{T_2+T_1}\)

Answer 1

The Correct Option is C

The correct option is (C) : \(\frac{l_1T_2-l_2T_1}{T_2-T_1}\)
