F = k×[tex]\frac{q1q2}{r2}[/tex]
Explanation:
- The attractive or repulsive forces which act between any two charged species is an electric force.
- The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows
F = k×[tex]\frac{q1q2}{r2}[/tex]
where, K is coulombs constant, which is equal to - 9 x10^9 [tex]Nm^2/C^2.[/tex]
- The unit for K is newtons square meters per square coulombs.
- This is known as Coulomb's Law.
