In the above question, if the sheets were thick and conducting , value of E in the space between the two sheets would be

In the above problem the value of E in the space outside the sheets is .

Two thin infinite sheets have uniform surface densities of charge +sigma and - sigma . Electric field in the space between the two sheets is

In a parallel plate capacitor of capacitance C, a metal sheet is inserted between the plates, parallel to them. The thickness of the sheet is half of the separation between the plates. The capacitance now becomes

A mica sheet has a thickness equal to the separation between the two plates of a parallel plate air capacitor. How would the capacitance change if the mica sheet is partially introduced in the space between the plates.
