A force is applied to a steel wire 'A', rigidly clamped at one end. As a result elongation in the wire is 0.2 mm0.2 \mathrm{~mm}0.2 mm. If same force is applied to another steel wire ' B\mathrm{B}B' of double the length and a diameter 2.42.42.4 times that of the wire 'A\mathrm{A}A', the elongation in the wire 'B\mathrm{B}B ' will be (wires having uniform circular cross sections)
