Question 120 of 180

A parallel plate condenser with a dielectric of dielectric constant K\mathrm{K} between the plates has a capacity C\mathrm{C} and is charged to a potential  V volts\mathrm{~V ~volts}. The dielectric slab is slowly removed from between the plates and then reinserted. The net work done by the system in this process is
