electrons transfer from one object to another when the objects touch.
Charge by Induction
a multistep process which is begun by bring a charged object near a neutral one, thus polarizing the object, followed by grounding the object and finally disconnecting the object-thus charging it.
Transfer of electrons from a polarized object to the earth.
a field force, that is both attractive and repulsive and varies inversely as the square of the distance between charges.
Resultant Force on a Charge
is the vector sum of the individual forces (components) on that charge.
For two charged objects that are much smaller than the distance between them, the force between the two objects varies directly as the product of their charges and inversely as the square of the separation distance.
a field that permeates the space around a charged object and in which another charged object experiences and electric force
