\(\vec{A}\) is a vector quantity such that \(|\vec{A}|=\) nonzero constant. Which of the following expressions is true for \(\vec{A}\) \(?\)
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) \(\overrightarrow{ A } \times \overrightarrow{ A }=0\)
Step-by-step Solution
Detailed explanation
\(|\overrightarrow{ A }| \neq 0\)
\(\overrightarrow{ A } \times \overrightarrow{ A }=|\overrightarrow{ A }||\overrightarrow{ A }| \sin 0^{\circ} \hat{ n }=0\)
