Two wires made of same material are clamped rigidly at one end and pulled by the same force on the other end. The length and the radius of the first wire are three times those of the second wire. If \(x\) is the increase in the length of the first wire, then the increase in the length of the second wire is
- A \(\frac{1}{3} x\)
- B \(3 x\)
- C \(9 x\)
- D \(\sqrt{3} x\)
Answer & Solution
Correct Answer
(B) \(3 x\)
Step-by-step Solution
Detailed explanation
As wires are of same material so both are having same young's modulus \(\Rightarrow \quad Y_1=Y_2\) \(\Rightarrow \quad \frac{\frac{F_1}{A_1}}{\frac{\Delta L_1}{L_1}}=\frac{\frac{F_2}{A_2}}{\frac{\Delta L_2}{L_2}}\)…
