Any dielectric material other than vacuum has a maximum electric field that can be produced in the dielectric material before it physically or chemically breaks down and begins to conduct. This maximum electric field is called dielectric strength. The dielectric strength for a particular material is reached at a value of 3.1 x 107 V/m. Calculate the maximum charge that can be placed on the capacitor of plate separation 0.4 cm and of C = 57 pF at this dielectric strength.
i am very very confused with this question, please help.
