Two small balls of the same size and of mass `m_(1)` and `m_(2)(m_(1) gt m_(2))` are tied by a thin light thread and dropped from a large height. Determine the tension `T` of the thread during the flight after the motion of the balls has become steady. (Air resistance force is same on two balls)
[Take `m_(1)=2kg`, `m_(2)=1kg`, `g=10m//s^(2)`]

Explanation

`m_(1)g-T-F=0`
`m_(2)g-T-F=0`
`rArr T=((m_(1)-m_(2))/(2))g=5`
