Find the unit vector along the given vector of magnitude .

Unit vectors.
A vector is said to be a unit vector with a unit magnitude. Another name for a unit vector is a direction vector. It is represented by a lowercase letter with the symbol of the cap (^). Unit vectors can be used to represent a vector in space. By dividing any vector by its magnitude, any vector may be converted into a unit vector:

Unit Vector = Vector/Magnitude of Vector
A unit vector “p” having the same direction as vector p is given as:

Where
Unit vector p (with cap symbol) represents a unit vector
p represents the vector
|p| represents the magnitude of the vector
Just because unit vectors p and q have the same magnitude does not mean that they are equal unit vectors. These unit vectors are distinct from one another because of the directions of the vectors. Therefore, both magnitude and direction must be provided in order to define a vector.
