#F=k(Q_1,Q_2)/r^2#

Explanation:

assume there are two charges #Q_1, Q_2#

the force between them can be found through this relation

#F=k(Q_1*Q_2)/r^2#

Where k is Coulomb's constant
and #r# is the distance between the two charges

and the force is attraction if the two charges have different sign
(#+ve and -ve#)
and repulsion if the two charges have the same sign
