Question

Two parallel plates have charges +Q and −Q to face each other at certain distance. The plates are dipped in kerosene oil tank. Electric field between the plates will:

G1 Physics · Accepted Answer

Step 1: Original field E₀ = σ/ε₀ between oppositely charged plates. Step 2: Kerosene dielectric constant K > 1 reduces field for fixed free plate charge. Step 3: New field E = E₀/K < E₀.
