1.	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: (a) case (i) contradicts Gauss’s law for electrostatic fields. (b) case (ii) contradicts Gauss’s law for magnetic fields. (c) case (i) agrees with ∮ E.dl = 0 . (d) case (ii) contradicts en ∮ H.dl = Ien
Answer» (b) case (ii) contradicts Gauss’s law for magnetic fields.
