The unit of electric permittivity is

The unit of electric permittivity is (C^(2))/(Nm^(2)) . Find the dimesions of electric permittivity

The unit of absolute permittivity is

An electromagnetic wave travels at a speed of 0.8 c in medium .Determine the value of relative permittivity of the medium if value is

A capacitor is composed of two plates separated by a sheet of insulating material 13 mm thick and or relative permittivity 4. The distance between the plates is increased to allow the insertion of second sheet 5 mm thick and of relative permittivity in_(r) . If the capacitance of the capacitor so formed is 1/3 of the original capacitance , find in_(r) .

An air capacitor with plates of area 1 m^(2) and 0.01 metre apart is charged with 10^(-6) C of electricity. When the capacitor is submerged in oil of relative permittivity 2 , then the energy decreases by.
