CHARGE (in terms of e and p)
An electrically neutral atom is an atom which....
What is balance of protons and electrons
Materials through which electrons can move easily are classified as...
What is a conductor
Electric force in an electric field is measured in what?
Newtons
The q value in Coulombs equation is in units of what?
Coulombs
process where charges are separated in object but the object remains neutral.
What is polarization.
An electrically charged atom can be distinguished from an electrically neutral atom in that the charged atom
What is imbalance of protons and electrons (unequal)
Insulators are different than in that insulators...
What is do not allow charge to freely move/migrate to the point of charge
In the equation F = qE, what is the q ?
The charge in Coulombs
The unit r in Coulombs equation is in units of what?
meters
Type of charging where two objects are rubbed together
What is charging by friction.
This is the name of an atom that has an unbalanced number of electrons and protons, resulting in a charge
What is an ion
What happens to electrons when charging two objects by rubbing them together
Some of the electrons must have transferred to the other object
Electric Field, E has what kind of displacement units in it?
meters
The F is measured in units of what in Coulombs equation?
newtons
Type of charging where a conductor is touched with a charged object.
What is conduction
-1.602 x 10-19 Coulombs is the charge of what?
1 electron
Rabbit fur is rubbed against a glass rod, which of these receives extra electrons?
the fur gets more electrons
Electric field is measured in what two units?
Newtons and coulombs
If you double q2 and keep r the same, what happens to the force between charges?
doubles
Type of charging where you get a charged object near a conductor but do not touch it. The conductor is then grounded which allows the charges to move off or onto the conductor.
What is induction
The charge of 2 protons
+3.2 x 10-19 Coulombs
When a glass rod is rubbed with silk what is the net new charge on the glass rod?
positive
A particle is producing a net force of 100 Newtons downward and is being levitated by an electric field of strength 1000 N/C, what is the charge on the particle?
0.1 Coulombs
If you double the r value and keep the q values constant, what happens to the Force?
decreases by 1/4
what is negative
