A uniform rectangular block of mass 50 kg is hung horizontally with the help of three wirres 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 made of a material of Young's modulus 7.5 × 1010 Nm–2 and the other two wires A and C symmetrically placed on either side of the wire B are of Young'smodulus 1011 Nm–2. The tension in the wires A and B will be in the ratio of
