Question

If for two vectors $\overset{\rightarrow}{A}$ and $\overset{\rightarrow}{B},\overset{\rightarrow}{A} \times \overset{\rightarrow}{B} = 0,$ the vectors

• A. Are perpendicular to each other
• B. Are parallel to each other
• C. Act at an angle of 60°
• D. Act at an angle of 30°

Answer 1

Answer: (B)

Are parallel to each other

Answer 2

$\overrightarrow{A} \times \overrightarrow{B} = 0$∴ $\sin\theta = 0$∴ $\theta = 0{^\circ}$

Two vectors will be parallel to each other.
