A capacitor is composed of 2 plates separated by a sheet of insulating material 2mm thick and of relative permittivity 3. The distance between the plates is increased to allow the insertion of a second sheet of 3mm thick and of relative permittivity ɛ,r. If the equivalent capacitance is one-half of the original capacitance, find the value of ɛp.
