StateCoulomb's law . |

Answer» Solution :Statement : The electrostaticforce between two point charges is DIRECTLY proportional to the product of MAGNITUDE of charges and inversely proportional to the SQUARE of the distance between them . The direction of this forceis along the line joining the two charges. Explanation : Let `q_(1)andq_(2)` be the magnitudes of two charges separatedby a distance rLet F be the force between them . From COULOMB .s LAW, `Fprop(q_(1)q_(2))/(r^(2))rArrF=(1)/(4piepsilon_(0))(q_(1)q_(2))/(r^(2))` Where `epsilon_(0)` is the absolute permittivity of free space. |
