Permittivity of Medium

Permittivity of Medium

### Formula

$$\epsilon=K\epsilon_0$$

### Terminologies

- ε → Permittivity of medium.

- K → Dielectric constant.

- ε₀ → Permittivity of vacuum.

### Conditions / Special Cases

Force in medium:

$$F=\frac{1}{4\pi\epsilon}\frac{q_1q_2}{r^2}$$

### Usage

- Used when charges are placed inside dielectric materials.
