JEE Mains · Physics · STD 11 - 3.1 vectors
If \(\overrightarrow{ P } \times \overrightarrow{ Q }=\overrightarrow{ Q } \times \overrightarrow{ P },\) the angle between \(\overrightarrow{ P }\) and \(\overrightarrow{ Q }\) is \(\theta\left(0^{\circ} < \theta < 360^{\circ}\right) .\) The value of \(\theta\) will be ........
- A \(90\)
- B \(135\)
- C \(180\)
- D \(45\)
Answer & Solution
Correct Answer
(C) \(180\)
Step-by-step Solution
