A metal slab of thickness, equal to half the distance between the plates is introduced between the plates of a parallel plate capacitor as shown. Find its capacity. .

A parallel plate air condenser has a capacity of 21 mu F . What will be the new capacity if A marble slab of dielectric constant 8 is introduced between the two plates?

The plates of a parallel plate capacitor with air as medium are separated by a distance of 8 mm . A medium of dielectric constant 2 and thickness 4 mm having the same area is introduced between the plates. For the capacitanace to remain the same, the distance between the plates is
