Question

two blocks of mass 2.9 kg and 1.9 kg are suspended from a rigid support by 2 inextensible wires each of length 1m. upper wire has a negligible mass and the lower wire has uniform mass of 0.2 kg/m. the whole system of blocks , wire and support have an upward acceleration of 0.2 m/s^2.

Answer 2

Two blocks A and B of masses 2.9kg and 1.9kg respectively are suspended with the help of two inextensible wires each of the length 1m from a rigid support as shown in the figure. The mass of the upper wire is negligible and that of the lower wire 0.2kg/m. This system of block, wires and rigid support is moving upwards with an acceleration of 0.2m/s
