Two blocks of masses 2.9 kg. and 1.9 kg. are suspended from a rigid supports by two inextensible wires each of length, lm. 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/s2 (g = 9.8 m/s2). The tension at the A mid-point of lower wire is?

The lower wire is uniform and therefore the Tension at the middle of the rope would be => 0.1 kg.
The FBD of the lower block and the eqn. for that would be:
=> T – mg = ma
or
T = mg + ma => m(g +a) => (1.9 + 0.1)(9.8+0.2) = 20 N.
