What do you mean by equilibrant vector ?

Explanation

### Step-by-Step Solution

1. **Understanding Forces Acting on an Object**:
- Consider an object (like a block) that is subjected to multiple forces. For example, let’s say there are three forces acting on this block in different directions.

2. **Identifying Net Force**:
- When multiple forces act on an object, they combine to produce a net force (F_net). This net force determines the acceleration of the object according to Newton's second law of motion (F = ma).
