If the line \(5 x-2 y-6=0\) is a tangent to the hyperbola \(5 x^2-k y^2=12\). then the equation of the normal to this hyperbola at the point \((\sqrt{6}, p)(p \lt 0)\) is

  1. A \(\sqrt{6} x+2 y=0\)
  2. B \(2 \sqrt{6} x+3 y=3\)
  3. C \(\sqrt{6} x-5 y=21\)
  4. D \(3 \sqrt{6} x-y=21\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\sqrt{6} x-5 y=21\)

Step-by-step Solution

Detailed explanation

Given equation of hyperbola \(5 x^2-k y^2=12\) \(\Rightarrow \frac{x^2}{\frac{12}{5}}-\frac{y^2}{\frac{12}{k}}=1\) So equation of tangent at \(\left(x_1, y_1\right)\) is…
