Two unlike charges such as a POSITIVE and a negative charge________________
neutralize each other.
repel each other.
must be neutrons.
attract each other.
when an atom loses an electron, what type of charge does it have now?
positive
negative
Where do some electrons from your hair go when you rub a balloon on your hair?
they get attached onto the balloon
they all remain on your hair
electrons don's usually move
It is the protons that flow
What do you call the process of charging an object by bringing a charged object near it?
induction
polarization
neutralization
conduction
The law of conservation of charge states that...
all atoms have more protons than electrons
only protons can be rubbed off of an atom
charge cannot be created or destroyed, the net charge remains unchanged
charge cannot be transferred
A negatively charged rod is brought near a neutral electroscope. This causing the negative charges in the rod repel the negative charges of the electroscope. When a person touches the top part of the electroscope, electrons flow in from the ground to neutralize the positives that are closer at the top due to attraction to the negative rod. Withdrawing the hand and the rod leaves causes the leaves to of the electroscope to diverge (move apart from each other). This is an example of what type of charging?
Conduction
induction
Insulation
Friction
Electric charges that are alike (positive and another positive) _______ each other.
Attract
Repel
What is the end result of charging by contact?
Both object have the same charge, so they will attract one another
Both object have the same charge, so they will repel one another
Both object have the opposite charge, so they will attract one another
Both object have the opposite charge, so they will repel one another
What is the name of this device or scope that is used to detect charges?
beaker
electroscope
van de graff generator
chargometer
Insulators are different from conductors in that insulators ____.
do not contain electrons or protons
do not contain any charge
have a weaker affinity for electrons
do not allow charge to freely move
If you increase the magnitude of two charges, what happens to the force between them?
The force is less than before
The force is more than before
The force remains unchanged
What is the force between 10 C and 5 C charges placed 1 m apart?
4.5 x 1010 N
1.24 x 108 N
4.5 x 109 N
4.5 x 1011 N
Two equal charges at 12 m exert a force of 0.35 N. What is the magnitude of each charge?
1.5 x 10-5
7.5 x 10-9
1.5 x 10-8
7.5 x 10-5
What types of charges attract?
Positive and Positive
Positive and Neutral
Negative and Neutral
Positive and Negative
Plastic is an example of _______.
an insulator
a conductor
Materials that tightly hold on to their electrons are considered
Good conductors
Good insulators
Good anti-static agents
Useful for storing charge
If two objects with static charge are attracted, what do you know about them?
They are both positively charged.
They are both negatively charged.
One is positively charged and the other negatively charged, but you won't be able to tell which is which.
One is positively charged and one is negatively charged, and you can tell which is which by looking at them.
Atoms and objects may become charged as the result of
losing protons
gaining protons
losing or gaining electrons
losing or gaining neutrons
If you double both charges and double the distance between them, what happens to the force?
The force is less than before
The force is more than before
The force remains unchanged
