सदिश \((\overrightarrow{ A })\) तथा \((\overrightarrow{ A }-\overrightarrow{ B })\) के बीच कोण है।

  1. A \(\tan ^{-1}\left(\frac{-\frac{{B}}{2}}{{A}-{B} \frac{\sqrt{3}}{2}}\right)\)
  2. B \(\tan ^{-1}\left(\frac{{A}}{0.7 {B}}\right)\)
  3. C \(\tan ^{-1}\left(\frac{\sqrt{3} {B}}{2 {A}-{B}}\right)\)
  4. D \(\tan ^{-1}\left(\frac{{B} \cos \theta}{{A}-{B} \sin \theta}\right)\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\tan ^{-1}\left(\frac{\sqrt{3} {B}}{2 {A}-{B}}\right)\)

Step-by-step Solution

Detailed explanation

Angle between \(\overrightarrow{{A}}\) and \(\overrightarrow{{B}}, \theta=60^{\circ}\) Angle betwenn \(\overrightarrow{{A}}\) and \(\overrightarrow{{A}}-\overrightarrow{{B}}\) \(\tan \alpha=\frac{B \sin \theta}{A-B \cos \theta}\)…
