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

To solve the problem, we need to analyze the forces acting on both balls after they have been dropped and the motion has become steady.

### Step-by-Step Solution:

1. **Identify the Masses and Forces:**
- Let \( m_1 = 2 \, \text{kg} \) (the heavier ball) and \( m_2 = 1 \, \text{kg} \) (the lighter ball).
- The gravitational force acting on each ball is given by \( F_g = m \cdot g \), where \( g = 10 \, \text{m/s}^2 \).
- Therefore, the weight of \( m_1 \) is \( W_1 = m_1 \cdot g = 2 \cdot 10 = 20 \, \text{N} \).
