A combination of parallel plate capacitors is maintained at a certain potential difference.
When a $\displaystyle 3$ mm thick slab is introduced between all the plates, in order to maintain the same potential difference, the distance between the plates is increased by $\displaystyle 2.4$ mm. Find the dielectric constant of the slab.
