A uniform rectangular block of mass 50 kg is hung horizontally with the help of three wires A. B and C each of length and area of 2 m and 10 mm2 respectively as shown in the figure. The central wire is passing through the centre of gravity and is madeof a material of Young's modulus 7.5 x 1010 Nm−2 and the other two wires A and C symmetrically placed on either side of the wire B are of Young's modulus 1011Nm−2 The tension in the wires A and B will be in the ratio of
