A force is applied to a steel wire 'A', rigidly clamped at one end. As a result elongation in the wire is $\displaystyle 0.2$ mm . If same force is applied to another steel wire ' B ' of double the length and a diameter $\displaystyle 2.4$ times that of the wire ' A ', the elongation in the wire 'B' will be (wires having uniform circular cross sections)
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle 6.9 \times 10^{-2} \mathrm{~mm}$
