A steel wire of length 3.2 m (YS = 2.0 × 1011 Nm–2) and a copper wire of length 4.4 M (YC = 1.1 × 1011 Nm–2), both of radius 1.4 mm are connected end to end. When stretched by a load, the net elongation is found to be 1.4 mm. The load applied, in Newton, will be:
(Given π = 22/7)
(A) 360
(B) 180
(C) 1080
(D) 154
