A parallel plate condenser with a dielectric of dielectric constant K between the plates

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