Unit of electric flux - Study guides, Class notes & Summaries

Electric charge A fundamental property of matter that can be either positive or negative Induced charge Static charge caused by the presence of an already charged object Coulomb's law Inverse square law, Electric Force = F = k * (q₁q₂)/r² = 1/(4πε₀) * (q₁q₂)/r Electrostatic force Force between electrically charged objects. Electric field Force that a source charge would exert on a positive test charge q₀ within its proximity divided by that test charge; E = F/q₀ ...
