The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied?NEET 2013 (All India)

Options:

Answer:

Solution:

$Δ L = \frac{F L}{A Y}$ or $Δ L \propto \frac{L}{d ^{2}} [∵ A = \frac{π d ^{2}}{4}]$ Therefore, $Δ$ will be maximum for that wire which $\frac{L}{A}$ is maximum, so option (1) is correct.
