A parallel plate condenser with a dielectric of dielectric constant $\mathrm{K}$ between the plates has a capacity $\mathrm{C}$ and is charged to a potential $\mathrm{~V ~volts}$. The dielectric slab is slowly removed from between the plates and then reinserted. The net work done by the system in this process is
  1. $1 / 2(\mathrm{~K}-1) \mathrm{CV}^2$
  2. $\mathrm{CV}^2(\mathrm{~K}-1) / \mathrm{K}$
  3. $(\mathrm{K}-1) \mathrm{CV}^2$
  4. zero
