Q.A parallel plate capacitor has plates of area $A$ separated by distance $d$ . It is filled with a dielectric of dielectric constant $K=3$ . The force of attraction between the plates is (JEE Main 2022)

\dfrac{3 \epsilon_0 A V^2}{2 d^2}

\dfrac{\epsilon_0 A V^2}{2 d^2}

\dfrac{9 \epsilon_0 A V^2}{2 d^2}

\dfrac{\epsilon_0 A V^2}{6 d^2}

The correct solution involves applying the fundamental concept to derive the final value step by step...
