Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
2D प्रवाह के लिए, धारा रेखा का समीकरण दिया गया है:
\( \frac{dx}{u} = \frac{dy}{v} \)
दिया गया है:
\( u = -y^2, \quad v = -6x \)
इसलिए,
\( \frac{dx}{-y^2} = \frac{dy}{-6x} \Rightarrow \frac{dx}{y^2} = \frac{dy}{6x} \)
तिर्यक गुणा करने पर:
\( 6x \, dx = y^2 \, dy \)
दोनों पक्षों का समाकलन करने पर:
\( \int 6x \, dx = \int y^2 \, dy \Rightarrow 3x^2 = \frac{y^3}{3} + C \)
3 से गुणा करने पर:
\( 9x^2 - y^3 = C \)
बिंदु (1,1) का उपयोग करने पर:
\( 9(1)^2 - (1)^3 = 8 \Rightarrow C = 8 \)
