F = K Q1 Q2/R2 F . . .

the force between two charges

K . . .

a constant, which you don't have to worry about right now;

It makes the units come out right, and it also accounts for the electrostatic

properties of the substance, medium, or space between the charges.

Q1, Q2 . . .

the size and sign of each charge

R . . .

the distance between the charges, or between their centers

if they're spread out
