atoms
Just as "gravity" is the study of a wide range of gravitational interactions, "electricity" is the study of a wide range of
electrical interactions.
To become a negative ion, an atom must do this
gain and electrons
Particle A has twice the charge of nearby particle B. Compared to the force on Particle A, the force on Particle B is this
the same
An electroscope is charged positively as indicated by foil leaves that stand apart. As a negative charge is brought close to the electroscope, the leaves do this
come closer together
Every isolated proton in the universe is surrounded by its own one of these two things
electrical and magnetic field
This is the force that binds atoms together to form molecules
electrical.
A positive ion has more of these than it has electrons
protons
Charge carriers in a metal are electrons rather than protons because electrons are bound this way
loosely
A balloon will stick to a wooden wall if the balloon is charged either positively or this
negatively
The electric field between oppositely-charged parallel plates has this characteristic
it is uniform
A fundamental rule of electricity is this
like charges repel and unlike charges attract
If electrons are stripped from an atom it becomes this
a positive ion
Two charged particles repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is also doubled, then the force will be this
F/2
If you rub an inflated balloon against your hair and place the balloon against the wall it will stick to the wall, illustrating this
charge polarization
Much of the charge on a conducting cube is mutually repelled in this direction
towards its corners
In an electrically neutral atom the number of protons in the nucleus is equal to the number these
electrons that surround the nucleus
It is said that electric charge is conserved, which means that electric charge
cannot be created or destroyed
Conducting materials are composed of atoms with these
loose outer electrons
Two charged particles held close to each other are released. As they move, their speeds increase. Therefore, their charges have either the same sign or this
Normally a small party balloon charged to several thousand volts will have a relatively small amount of these two things.
charge and energy
This is an electrically charged atom
ion
Magnitude and separation distance are two factors that influence the electrical force between these
electric charges
An uncharged pith ball is suspended by a nylon fiber. When a negatively-charged rubber rod is brought near the pith ball, without touching, the ball does this
becomes polarized
Two charges separated by one meter exert 1-N forces on each other. If the charges are pulled 3 meters apart, the force on each charge will be this
0.11 Newtons
When a car is struck by lightning, the resulting electric field inside the car is this
zero
