Answer 2

Answer:

The correct  answer to the above question is-

(a) unity

Explanation:

Properties of Unit of vector-

• The magnitude of a unit vector is unity.
• A unit vector has no units or dimensions.

• A unit vector has a magnitude of 1.
• Unit vectors are only used to specify the direction of a vector Unit.  Vector exist in both two and three-dimensional planes.
• Every vector has a unit vector in the form of its components.

Direction vector

A vector that has a magnitude of 1 is a unit vector. It is also known as a direction vector because it is used to denote the direction of a vector.
