Question

What is unit vector??​

Answer 1

Explanation:

whose magnitude is 1.

unit vector a,=vector a/ magnitude of vector a

Answer 2

Unit Vector:-

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 A is written as A^ and is read as A cap.

A = |A|*A^

where |A| = magnitude of A

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- I cap j cap and k cap  are the unit vectors along x axis , y axis and z axis respectively.

Note:-

A-------》 repents the vector and should be called as A bar.
