what do you mean by unit vectors?
A vector of unit magnitude is called a unit vector . It has the same direction as that of the given vector .
A unit vector of is written as and is read as A cap.
= A Or
where A = magnitude of .
So, a unit vector in a given direction can also be defined as a vector in that direction divided by the magnitude of the given vector.
It has not unit and dimension. It represents direction only.
Example- are the unit vectors along x axis , y axis and z axis respectively.

a vector which has magnitude 1
a vector having magnitude 1 .
See…A unit vector has magnitude 1, with no units. The unit vector is represented by a letter marked with a hat. a unit vector has a magnitude 1, with no units, means that if you multiply a unit vector by a scalar, the resulting vector has a magnitude equal to the value with- units of the scalar. Hope u understood :)
