Answer the following as true or false.(i) ` -> a`and `- -> a`are collinear.(ii) Two collinear vectors are always equal in magnitude.(iii) Two vectors having same magnitude are collinear.(iv) Two collinear vectors having the same magni

Explanation

To solve the question, we need to analyze each statement regarding collinear vectors and determine whether they are true or false.

### Step-by-Step Solution:

1. **Statement (i)**: `→a` and `−→a` are collinear.
- **Explanation**: Two vectors are said to be collinear if they lie on the same line or are parallel to each other. The vector `→a` points in one direction, while `−→a` points in the exact opposite direction. Since they are parallel (both lie along the same line), they are indeed collinear.
- **Conclusion**: This statement is **True**.
