The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. when a voltage of 76.2 v is put across the plates of such a capacitor an electric field strength of 2.2 kv cm is measured. write an equation that will let you calculate the distance d between the plates. your equation should contain only symbols. be sure you define each symbol.
