For 5 kg block,
50 Sin30° - T1 = 5a -----(1)
For 3 Kg block,
30 Sin30° + T1 - T2 = 3a ----(2)
For 2 kg block,
T2 - 20 = 2a -----(1)
Adding all the equations we get,
20 = 10a
a = 2 ms-²
Putting this in equation (1)&(2) respectively.
50 × 1/2 - T1 = 5 × 2
T1 = 15 N
Again,
T2 - 20 = 2 × 2
T2 = 24
Ratio,
T1/T2 = 15/24
T1:T2 = 5:8 Answer......
