Electric charge the charge of an electron is negative, "−e", while that of a proton is positive, "+e". Charged particles whose charges have the same sign repel one another, and particles whose charges have different signs attract. Coulomb's law quantifies the electrostatic force between two particles by asserting that the force is proportional to the product of their charges, and inversely proportional to the square of the distance between them. The charge of an antiparticle equals that of the corresponding particle, but with opposite sign. The electric charge of a macroscopic object is the sum of the electric charges of the particles
Aonghas (given name) Aonghas (given name) Aonghas is a masculine given name in Scottish Gaelic. It is composed of Celtic elements meaning "one", and "choice". A variant spelling of the Scottish Gaelic name is "Aonghus". The Irish form of the Scottish Gaelic names is "Aengus".
