Distance is increased-

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

$\frac{1}{4}$
$4$
$3$
$1$

Distance is increased.

When a dielectric slab of thickness 4cm is introduced between the plates of parallel plate condenser, it is found that the distance between the plates has to be increased by 3cm to restore the capacity to it's original value. The dielectric constant of the slab is14431
