The equation for an electrical force between two point charges:
F = k*q1*q2/r^2, where
F = the attractive or repulsive electrical force [N]
k = electrical constant = 8.99x109 [N m2 C-2]
q1 and q2 are the magnitude of the two point charges in question [C]
r = the separation between the two point charges [m]
------------------------------------------------------------------------------------
Since q1 = 3 [C] and q2 = -3 [C], F is negative in sign --> attractive force. Rearranging the force expression, we have
r = sqrt {k*q1*q2/F} = sqrt {-8.99x109*3*3/-1} = 2.844x105 [m].
==============================
They balance the atomic charge and electrical forces.
They attract their opposite forces are attracted to each other.
Ionic compounds contain positive and negative ions, which bond together by electrostatic forces. The net charge is zero of a sample of an ionic compound.
The Na atom and the Cl atom of the molecule NaCl form what is known as an ionic bond. Basically the Sodium atom (Na) has a positive charge, while the chlorine atom (Cl) has a negative charge. Just like with magnets, the positive and the negative charge attract to each other.
Because a nonpolar molecule has no overall charge, it will not interact with a positive force.
When a positive and negative charge collide, their forces act in the same direction, from positive to negative. As a result, contrary charges are attracted to one another: the electric field and forces produced by two electrical charges of opposite polarity. Both charges are attracted to each other.

They balance the atomic charge and electrical forces.
Positive forces can counter negative forces.
They attract their opposite forces are attracted to each other.
Ionic compounds contain positive and negative ions, which bond together by electrostatic forces. The net charge is zero of a sample of an ionic compound.
An isolated positive and negative can move for example in an electric or magnetic field. But in metals only the electrons can move since the positive charge is bound to the metal lattice by attractive forces.
Positive and negative
Dipole forces are attractive forces between the positive end of one polar molecule and negative end of another polar molecule. These forces have strength from 5kj to 20kj per mole.
The Na atom and the Cl atom of the molecule NaCl form what is known as an ionic bond. Basically the Sodium atom (Na) has a positive charge, while the chlorine atom (Cl) has a negative charge. Just like with magnets, the positive and the negative charge attract to each other.
It need not have a negative charge. In fact, it should usually be uncharged. Electrical and magnetic forces should be treated as different forces.
The strong forces of attraction between the positive and negative regions of molecules are called electrostatic forces or electrostatic interactions.
