Definition of Coulomb's law in English:

Coulomb's law

  • A law stating that like charges repel and opposite charges attract, with a force proportional to the product of the charges and inversely proportional to the square of the distance between them.

    • ‘Among these was Coulomb's law in electrostatics.’
    • ‘The importance of Coulomb's law for the development of electromagnetism is examined and discussed.’
    • ‘The analytical expression for this energy was obtained in the form of Coulomb's law with an effective distance-dependent dielectric function.’
    • ‘The main assumptions are that the plate boundary follows Coulomb's law of shear strength, and that the plate is an elastic homogeneous and isotropic body.’
    • ‘He did this by equating Coulomb's law to Newton's equations of motion.’


Late 18th century: named after C.-A. de Coulomb (see coulomb).
