📌 Explanation: Polarization of Dielectric

Step 1 — External Field Applied (E₀):

• External electric field <b>E₀</b> is applied to the dielectric.

Step 2 — Polarization Occurs:

• The external field causes slight separation of positive and negative charges within molecules.
  • This creates an <b>induced electric field E_p</b> (polarization field).
  • <b>E_p opposes E₀</b> (directed opposite).

Step 3 — Net Field Inside Dielectric:

E_net = E₀ − E_p = E₀ / K

Where <b>K = Dielectric Constant</b> (K &gt; 1)

Step 4 — Conclusion:

Since K &gt; 1, E_net &lt; E₀

∴ <b>Electric field inside the dielectric decreases</b> due to the opposing polarization field.
