In case of radial symmetry, ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2} ) is_________ |
| A. | ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2}= frac{ ^2 overline{u}}{ r^2}+ frac{1}{r} frac{ overline{u}}{ r} ) |
| B. | ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2}= frac{ ^2 overline{u}}{ r^2}- frac{1}{r} frac{ overline{u}}{ r} ) |
| C. | ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2}=- frac{ ^2 overline{u}}{ r^2}+ frac{1}{r} frac{ overline{u}}{ r} ) |
| D. | ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2}=- frac{ ^2 overline{u}}{ r^2}- frac{1}{r} frac{ overline{u}}{ r} ) |
| Answer» B. ( frac{ ^2 overline{u}}{ x^2}+ frac{ ^2 overline{u}}{ y^2}= frac{ ^2 overline{u}}{ r^2}- frac{1}{r} frac{ overline{u}}{ r} ) | |
