माना दीर्घवत्त \(\frac{ x ^{2}}{9}+\frac{ y ^{2}}{1}=1\) तथा वत्त \(x ^{2}+ y ^{2}=3\) के प्रथम चतुर्थाश में प्रतिच्छेदन बिन्दु पर स्पर्श रेखाओं के बीच न्यून कोण \(\theta\) है। तब \(\tan \theta\) बराबर है

  1. A \(\frac{5}{2 \sqrt{3}}\)
  2. B \(\frac{2}{\sqrt{3}}\)
  3. C \(\frac{4}{\sqrt{3}}\)
  4. D \(2\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{2}{\sqrt{3}}\)

Step-by-step Solution

Detailed explanation

The point of intersection of the curves \(\frac{x^{2}}{9}+\frac{y^{2}}{1}=1\) and \(x^{2}+y^{2}=3\) in the first quadrant is \(\left(\frac{3}{2}, \frac{\sqrt{3}}{2}\right)\) Now slope of tangent to the ellipse \(\frac{x^{2}}{9}+\frac{y^{2}}{1}=1\) at…
