Question

15.What is the magnitude of a unit vector​

Answer 1

Answer:

A vector has both magnitude and direction. A unit vector is a vector with magnitude of 1. A unit vector of v, in the same direction as v, can be found by dividing v by its magnitude

Answer 2

Answer:

Because a unit vector, by definition, has a magnitude of 1, so if you want a unit vector in the direction of A you need to divide by its magnitude.
