JEE Mains · Maths · STD 11 - 10.2 parabola,ellipse,hyperbola

પ્રથમ ચરણમાં રેખા \(y=m x\) અને ઉપવલય \(2 x^{2}+y^{2}=1\) બિંદુ \(\mathrm{P}\) આગળ છેદે છે . જો બિંદુ \(P\) આગળનો અભિલંભ અક્ષોને \(\left(-\frac{1}{3 \sqrt{2}}, 0\right)\) અને \((0, \beta)\) આગળ છેદે છે તો \(\beta\) મેળવો.

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

Answer & Solution

Correct Answer

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

Step-by-step Solution

Detailed explanation

Any normal to the ellipse is \(\frac{\mathrm{x} \sec \theta}{\sqrt{2}}-\mathrm{y} \cos \mathrm{ec} \theta=-\frac{1}{2}\) \(\Rightarrow \frac{\mathrm{x}}{\left(\frac{-\cos \theta}{\sqrt{2}}\right)}+\frac{\mathrm{y}}{\left(\frac{\sin \theta}{2}\right)}=1\)…
