MCQ
Consider the two idealized systems: $(i)$ a parallel plate capacitor with large plates and small separation and $(ii)$ a long solenoid of length$ L > > R$, radius of cross-section. In $(i)$ E is ideally treated as a constant between plates and zero outside. In $(ii)$ magnetic field is constant inside the solenoid and zero outside. These idealised assumptions, however, contradict fundamental laws as below:
- ACase $(i)$ contradicts Gauss’s law for electrostatic fields.
- ✓Case $(ii)$ contradicts Gauss’s law for magnetic fields.
- CCase $(i)$ agrees with $\oint\text{E.dl=0.}$
- DCase $(ii)$ contradict $\oint\text{H.dl}=\text{I}_\text{en}$.
