invent a time machine
go back 6 months and study your class material
way to complicated for "short answer"
C law is the force exerted by electric charge on each other
is is similiar to the idea of gravity force between masses
F the force between charges = K Q Q/r^2 where Q is the unit plus or minus of each charge in "columbs" a measure of how much charge
K a constant to get ht force unit correct and r the distance between the centers of the charges
why this is true , nobody knows. it is the way the univere is.
