    ‘He did this by equating Coulomb's law to Newton's equations of motion.’
    • ‘The analytical expression for this energy was obtained in the form of Coulomb's law with an effective distance-dependent dielectric function.’
    • ‘Among these was Coulomb's law in electrostatics.’
    • ‘The importance of Coulomb's law for the development of electromagnetism is examined and discussed.’
    • ‘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.’
