Two identical condensers M and N are connected in series with a battery. The space between the plates of 'M' is completely filled with dielectric medium of dielectric constant $$8$$ and a copper plate of thickness $$d/2$$ is introduced between the plates of N. (d$$ $$=$$ distance of separation of the $$plates). Then the potentials of M and N are respectively.
