Question

Define unit vector & write its expression​

Answer 1

Explanation:

A vector is a quantity which has both magnitudes, as well as direction. A vector which has a magnitude of 1 is a unit vector. It is also known as Direction 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.

Answer 2

UNIT VECTOR IS A VECTOR WITH MAGNITUDE ONE
