The unit vector of a vector A magnitude 2 is

C. A / 2

he unit vector of vector A (magnitude 2) is:

C. A / 2

Here’s why:

• A unit vector has a magnitude of 1. It represents the direction of the original vector but with a scaled down length of 1 unit.
• To find the unit vector, we take the original vector (A) and divide it by its magnitude.

In this case, the magnitude of the vector is given as 2. So:

Unit vector of A = A / |A| = A / 2

Therefore, option C (A / 2) is the correct answer.
