Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
अतिपरवलय का समीकरण, \(\rm \frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}= 1\)
नाभिलंब की लम्बाई, L.R = \(\rm\frac{2b^{2}}{a}\)
अतिपरवलय का समीकरण, \(\rm- \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}= 1\)
नाभिलंब की लम्बाई, L.R = \(\rm\frac{2a^{2}}{b}\)
गणना:
दिया गया समीकरण, 25y2 - 24x2 = 600 है।
⇒ \(\rm- \frac{x^{2}}{25}+\frac{y^{2}}{24}= 1\)
मानक समीकरण के साथ तुलना करने पर, a = 5 और b = \(2\sqrt{6}\)
हम जानते हैं कि, नाभिलंब की लम्बाई
L.R = \(\rm\frac{2a^{2}}{b}\) = \(\frac{2\times25}{2\sqrt{6}}\)
⇒ L.R = \(\frac{25}{\sqrt{6}}\) इकाई
सही विकल्प 1 है।
