For the resultant of two vectors \(\mathbf{A}\) and \(\mathbf{B}\) to maximum, the angle between them should be
- A \(180^{\circ}\)
- B \(0^{\circ}\)
- C \(90^{\circ}\)
- D \(60^{\circ}\)
Answer & Solution
Correct Answer
(B) \(0^{\circ}\)
Step-by-step Solution
Detailed explanation
We know that, the magnitude of resultant of two vectors \(\mathbf{A}\) and \(\mathbf{B}\), \(R=\sqrt{A^2+B^2+2 A B \cos \theta}\) Here, \(R \rightarrow R_{\max }\), when \(\cos \theta\) is maximum i.e. \(\cos \theta=1\) \(\theta=0^{\circ}\) Now, we get…
