A force is applied to a steel wire ‘A', rigidly clamped at one end. As a result elongation in the wire is 0.2 mm. If same force is applied to another steel wire 'B' of double the length and a diameter 2.4 times that of the wire 'A', the elongation in the wire 'B' will be (wires having uniform circular cross sections) (1) 6.06 x 10 mm (2) 2.77 x 10 mm (3) 3.0 × 10² mm (4) 6.9 × 10² mm
