Describe coulomb law of electric force between two charges

1-

Coulomb's law states that the electric force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between their centers. When applied to our two charges - the source charge (Q) and the test charge (q) - the formula for electric force can be written as
 
 

Where, k = 9.0 × 109 N.m2/C2

D = separation distance between charges (meters)
