Two blocks of masses 2.9 kg and 1.9 kg are suspended from a rigid support by two inextensible wires each of length 1 m, the upper wire has negligible mass and the lower wire has a uniform mass of 0.2 kg/m. The whole system of block, wire and support has an upward acceleration of 0.2 m/s2. (take g=9.8m/sec2) The tension at the mid-point of lower wire is:
