Formula
Formula: Solid Sphere (E-field Inside)

Electric field

Unit
Radial outwards directed electric field at the field point \( r \) within a homogeneously electrically charged sphere.

Electric charge

Unit
It is the amount of charge that is homogeneously distributed within the entire sphere.

Field point

Unit
Field point points from the center of the sphere to any point inside the sphere where the electric field \( E(r) \) is present.

Radius

Unit
Radius of the charged sphere.

Vacuum Permittivity

Unit
Vacuum permittivity occurs in electrical phenomena and is a physical constant with value \( \varepsilon_0 ~=~ 8.854 \,\cdot\, 10^{-12} \, \frac{\text{As}}{\text{Vm}} \).
