bodies are charged through friction, there is a transfer of electric charge
from one body to another, but no creation or destruction
of charge 5 Coulomb’s Law: The mutual electrostatic force between two point
charges q1 and q2 is proportional to the product q1q2 and inversely
proportional to the square of the distance r21 separating them
