State Coulomb's law ....

State Coulomb's law .

Text Solution

Verified by Experts

Statement : The electrostatic force 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 force is along the line joining the two charges.
Explanation : Let `q_(1)andq_(2)` be the magnitudes of two charges separated by a distance r Let 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.
