Question

# If a vector has magnitude 1, then the vector is called as

- Orthogonal vector
- Unit vector
- Time vector
- Null vector

Hint:

### If only Unit is written it means 1.

## The correct answer is: Unit vector

- We say that 2 vectors are orthogonal if they are perpendicular to each other.
- A vector is a quantity that has both magnitude, as well as direction. A vector that has a magnitude of 1 is a unit vector. It is also known as Direction Vector.
- A directionless vector whose magnitude is zero is called a null vector.
