Dielectrics

A parallel plate capacitor is charged by a battery and battery remains connected. The dielectric slab of constant ' $K$ ' is inserted between the plates and then taken out. Then electric field between the plates

Show answer and solution

Answer: (a)

Battery stays connected, so $V$ is fixed.
$E = \frac{V}{d}$ depends only on $V$ and $d$ , which are the same after the slab is taken out.
So the field remains the same: answer (a).
