Question

Two vectors of the same physical quantity are unequal if

• A. they have the same magnitude and the same direction
• B. they have different magnitudes but the same direction
• C. they have the same magnitude but different directions
• D. they have different magnitudes and different directions.

Answer 1

Answer: (B), (C), (D)

The correct options are
B they have different magnitudes but the same direction
C they have the same magnitude but different directions
D they have different magnitudes and different directions.

For many purposes, two vectors $\overrightarrow{A}and\overrightarrow{B}$ may be defined to be equal if they have the same magnitude and point in the same direction.
