When a dielectric slab of thickness `4 cm` is introduced between the plates of parallel plate condenser, it is found the distance between the plates has to be increased by `3 cm` to restore to capacity to original value. The dielectric constant of the slab is.

When a dielectric slab of thickness 6 cm is introduced between the plates of parallel plate condenser, it is found that the distance between the plates has to be increased by 4 cm to restore to capacity original value. The dielectric constant of the slab is

When a slab of inslulating material 4 mm thick is inroduced between the plates of a parallel plate capacitor, it is found that the distance between the plates has to be increased by 3.2 mm to restore the capacity to its original value. Calculate dielectric constant of the material.
