Question

If A bar + B bar = C bar and magnitude of A bar + magnitude of B bar = magnitude of C bar. Then the angle between A bar and B bar is

A) 45°
B) 60°
C) 90°
D) 0°

Answer 1

D) 0°

Step-by-step explanation:

If vectors A and B add up to vector C, then vector C must start where A starts and end where B ends.

Since we also know the magnitudes of A and B add up to the magnitude of C, then A, B, and C must be inline with each other.

Therefore, the angle between A and B is 0°.
