Detailed Solution
Download Solution PDFदिया गया है:
सतह x2 + y2 – z2 = 11 है
बिंदु (4, 2, 3) पर
प्रयुक्त सूत्र:
सदिश इकाई बिंदु 'n' पर सतह के लम्बवत होती है जैसे कि \(\frac{\hat{n}}{\hat{|n|}}\)
गणना:
\({\hat{|n|}} = \sqrt{4^2 + 2^2 + (-3)^2} = \sqrt{29}\)
∴ बिंदु (4, 2, 3) पर सतह x2 + y2 – z2 = 11 के लम्बवत सदिश इकाई = \(\frac{{4\widehat i + 2\widehat j - 3\widehat k}}{{\sqrt {29} }}\)
