Question

define unit vector with example. state it's significance.​

Answer 1

A vector is a quantity that has both magnitude, as well as direction. A vector that has a magnitude of 1 is a unit vector. For example, vector v = (1,3) is not a unit vector, because its magnitude is not equal to 1, i.e., |v| = √(12+32) ≠ 1
