The angular momentum of a particle changes from `4kg m^(2)s^(-1)` to `8kg m^(2)s^(-1)` is `2` seconds. Calcualte the torque acting on the particle

Explanation

To solve the problem of calculating the torque acting on a particle when its angular momentum changes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values**:
- Initial angular momentum, \( L_1 = 4 \, \text{kg m}^2/\text{s} \)
- Final angular momentum, \( L_2 = 8 \, \text{kg m}^2/\text{s} \)
- Time interval, \( \Delta t = 2 \, \text{s} \)
