A person of mass 50 kg stands on a weighing scale on a lift . If the lift is descending with a downward acceleration of `9ms^(-2)` what would be the reading of the weighing scale? `(g =10ms^(-2)) ` .

Explanation

To solve the problem, we need to determine the reading on the weighing scale when a person of mass 50 kg is in a lift that is descending with an acceleration of \(9 \, \text{m/s}^2\). The acceleration due to gravity \(g\) is given as \(10 \, \text{m/s}^2\).

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Mass of the person, \(m = 50 \, \text{kg}\)
- Acceleration due to gravity, \(g = 10 \, \text{m/s}^2\)
- Downward acceleration of the lift, \(a = 9 \, \text{m/s}^2\)
