Induced Charge On The Surface Of Dielectric

(a) A parallel plate capacitor of plate area 2m^(2) and pltae separation 5xx8.85mm is cahrged to 200V in vacuum. Comute the capacitance, charge, charge density and electric field. (b) The charging is removed and space between the plates is filled with a dielectric (K=5) . computer new capacitance, the p.d ., electric field and induced charge at the surface of dielectric slab. (c) If now the dielectric sheet is removed and replaced by two sheets, one 2xx8.85mm thick of dielectric constant 4 , and the other 3xx8.85mm thick of dielectric constant 2 , compute electric field in each dielectric, the potential difference across the capacitor and its capacitance.

Dielectric in Capacitor | Induced Charge and Force on Dielectric

A dielectric slab is inserted between the plates of a capacitor. The charge on the capacitor is Q and the magnitude of the induced charge on each surface of the dielectric is Q' .

In an isolted, charged, parllel-plate air capacitor, the charge per unit area on each plate has a magnitude of sigma . A dielectric slab having the dielectric constant K is now introduced between the plates. The induced charge per unit area on the surface of the dielectric will have magnitude.

The answer to each of the following questions is a single-digit integer ranging from 0 to 9. Darken the correct digit. A metal plate with total charge Q on it, is placed parallel to a dielectric slab of same area. Let q be the charge appearing on the surface of dielectric whose dielectric constant is 2. Calculate Q//q .

(b)The charging battery is disconnected and a dielectric of dielectric constant 2.5 is inserted . Calculate the new potential difference between the plate .(c) What charge would have producted this potential difference in absence of the dielectric slab.(d) Find the charge induced at a surface of the dielectric slab.
