Mention at least three conditions under which weight of a person can become zero.

Explanation

To determine the conditions under which the weight of a person can become zero, we can analyze three specific scenarios based on the principles of gravitation.

### Step-by-Step Solution:

1. **Understanding Weight**:
- Weight (W) is defined as the force exerted by gravity on an object. It is given by the formula:
\[
W = m \cdot g_{\text{effective}}
