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°

D) 0°

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°.
