PHYS 1260 EXAM 1 QUESTIONS WITH VERIFIED
ANSWERS
Just as "gravity" is the study of a wide range of gravitational interactions, "electricity" is
the study of a wide range of
Electrical Interactions
Electrostatics is a branch of electricity that focuses on.
electrical charge
The force that binds atoms together to form molecules is
electrical
The fundamental force underlying all chemical reactions is
electrical.
A fundamental rule of electricity is that
like kinds of charges repel and unlike kinds of charges attract
An electron and a proton
attract each other
The vast numbers of electrons in a coin don't fly off the surface because
they are attracted by an equal number of protons
To say that electric charge is conserved means that no case has ever been found
where
net charge has been created or destroyed
An electrically charged atom is an
Ion
It is said that electric charge is conserved, which means that electric charge
can be neither created nor destroyed
, To become a positive ion, an atom must
lose an electron
The unit of electric charge, the coulomb, is the charge on
specific large number of electrons
Two protons attract each other gravitationally and repel each other electrically. The
stronger of these two forces is
electrical
A main difference between gravitational and electric forces is that electrical forces
repel or attract
The electrical force between charges is strongest when the charges are
close together
The electrical force between electric charges depends only on their
magnitude and separation distance.
When the distance between two charges is halved, the electrical force between them
Quadruples
Particle A has twice the charge of nearby particle B. Compared to the force on Particle
A, the force on Particle B is
the same
Two charges that are separated by one meter exert 1-N forces on each other. If the
charges are pushed together so the separation is 25 centimeters, the force on each
charge will be.
16 N
Two charges that are separated by one meter exert 1-N forces on each other. If the
magnitude of each charge is doubled, the force on each charge is
4N
