The angle between \((\overrightarrow A - \overrightarrow B )\) and \((\overrightarrow A \times \overrightarrow B )\) is \((\overrightarrow{ A } \neq \overrightarrow{ B })\)
- A \(120\)
- B \(45\)
- C \(90\)
- D \(60\)
Answer & Solution
Correct Answer
(C) \(90\)
Step-by-step Solution
Detailed explanation
\(\overrightarrow{ A }, \overrightarrow{ B }, \overrightarrow{ A }-\overrightarrow{ B }\) are in same plane. \(\overrightarrow{ A } \times \overrightarrow{ B }\) is perpendicular to the plane of \(\vec{A}, \vec{B}\) and \(\vec{A}-\vec{B}\) then angle between \(\vec{A}-\vec{B}\) and \(\overrightarrow{ A } \times \overrightarrow{ B }\) is \(90^{\circ}\).
