Electric Field Inside Uniformly Charged Solid Sphere

Electric Field Inside Uniformly Charged Solid Sphere

### Formula

$$E=\frac{1}{4\pi\epsilon_0}\frac{Qr}{R^3}$$

### Terminologies

- E → Electric field inside sphere.

- Q → Total charge of sphere.

- r → Distance from centre.

- R → Radius of sphere.

### Conditions / Special Cases

At centre:

$$r=0$$

$$E=0$$

At surface:

$$r=R$$

$$E=\frac{1}{4\pi\epsilon_0}\frac{Q}{R^2}$$

### Usage

- Used in charged sphere problems.
