Question
Two blocks of masses 2.9 kg. and 1.9 kg. are suspended from a rigid supports by two inextensible wires each of length, 1m. 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 have an upward acceleration of 0.2 m/sec2 (g = 9.8 m/sec2). The tension at the mid-point of lower wire is
