Two identical dielectric slabs, A and B, are placed symmetrically between the plates X and Y of charged parallel-plate capacitor. The electric intensity has magnitudes `E_(1)//E_(2)` and `E_(3)` at the points `1, 2` and `3`

A dielectric slab is placed between the plates of a parallel plate capacitor. Its capacitance.

A parallel- plate capacitor is charged from a cell and then isolated from it. A dielectric slab of dielectric constant K is now introduced in the region between the plated, filling half of it. The electric intensity in the diaelectric is E_(1) and that in air is E_(2) .

Two thin dielectric slabs of dielectric constants K_1 and K_2 (K_1ltK_2) are inserted between plates of a parallel plate capacitor, as shown in the figure. The variation of electric field E between the plates with distance d as measured from plate P is correctly shown by
