The plates of a capacitor are connected to a source of `e.m.f 320 V`. Between the platesm there are two dielectric slabs each of uniform thickness filling the whole space. One slab `A` is of thickness `4 mm` and dielectric constant `8`. The other slab `B` is of thickness `3 mm` and dielectric constant `10`.

The plates of a parallel plate capacitor are separated by a distance d = 1 cm . Two parallel sided dielectric slabs of thickness 0. 7cm and 0.3cm fill the space between the plates. If the dielectric constants of the two slabs are 3 and 5 respectively and a potential difference of 440V is applied across the plates. Find (a) The electric field intensities in each of the slabs.

Separation between the plates of parallel plate capacitor is 5 mm. this capacitor, having air as the dielectric medium between the plates, is charged to a potential difference 25 V using a battery. The battery is then disconnected and a dielectric slab of thickness 3mm and dielectric constant K=10 is placed between the plates as shown. potential difference between the plates after the dielectric slab has been introduced is-

The separation between the plates of a capacitor of capacitance 2muF is 4mm. Initially there is air between the paltes. If two dielectric slabs of area of cross-section same as the capacitor, thickness 2mm each, and dielectric constant 3 and 5 respectively are introduced, the capacitance becomes (in muF )
