Can you give any situation where Gauss.s law cannot be helpful ? |
| Answer» SOLUTION :Consider an electric DIPOLE. The field does have axial SYMMETRY about the dipole axis but there is no SIMPLE surface over which normal componentof `bar E`is constant. So, practically it is difficult to apply Gauss.s law to such a system even though the law is valid in this SITUATION. | |
