A body of mass 8 kg is hanging another body of mas 12 kg. The combination is being pulled by a string with an acceleration of `2.2 m s^(-2)` . The tension `T_(1) and T_(2)` will be respectively: (use `g = 9.8 m//s^(2)` ) :

Options

A. 200 N, 80 N
B. 220 N, 90 N
C. 240 N, 96 N
D. 960 N, 96 N

Answer

C

Explanation

`T_(2)-80=8(2.2)" ……………(i)"`
`T_(1)-T_(2)-120=12(2.2)" ………………..(ii)"`
`T_(1)=240N, T_(2)=96N`
