Coulombs law describes the electrostatic force between two charged particlesIt states that the forceis directly proportional to the product of the charges and inversely proportional to the square of the distance between themThe formula for Coulombs law is F k q1 q2 r2 where F is the electrostatic force between the two charges in Newtons k is Coulombs constant 899 x 109 N m2C2 q1 and q2 are the charges of the two particles in Coulombs r is the distance between the two charges in meters The force between two charges can be either attractive or repulsivedepending on the signs of the chargesIf the charges have the same signthe force is repulsiveIf the charges have opposite signsthe force is attractive Mathematicallythe difference between attractive and repulsive interactions between ions is expressed by the sign of the forceWhen the force ...
