What is an Electric Field?
Where a particle has electric potential
A region where a particle with mass experiences a force
A region where a charged particle experiences a force
Where there is a constant electric field strength
In Coulomb's law, teh force between two charged particles is
proportional to the distance between them
directly proportional to the distance between them
inversely proportional to the distance between them
inversely proportional to the square of the distance between them
Equipotential lines are always
The same distance apart
increasing in distance apart
the same value
the same charge along the line
Electric field strength can be defined as
the force felt by a charge
the gradient of electric potential
the energy per coulomb in a field
the line of equal potential
A resultant force is required for circular motion. This is fundamentally due to
Newton's 1st law
Newton's 2nd law
Newton's 3rd law
Centripetal force
The feeling of weightlessness arises from
the lack of a normal contact force on an object
the lack of forces on an object
the lack of a resultant force on an object
the lack of gravity on an object
Antimatter can have opposite
mass
energy
lepton number
size
a baryon consists of how many quarks?
0
1
2
3
A hadron consists of
quarks
protons
neutrons
leptons
A meson consists of
2 quarks
2 quarks and one antiquark
a quark and an antiquark
2 antiquarks
A lepton is
a negative particle
a fundamental particle
a proton
a type of hadron
Quarks interact with
the weak force
the gravitational force
the electromagnetic force
the strong force
For thermionic emission the wire must be
hot
cold
moving
connected to a power supply
In a LINAC the electrons are accelerated by
the magnetic field
the drift tubes
the electric field
gravity
In a LINAC the field swaps due to the
alternating current
direct current
increasing length of the drift tubes
gaps in the drift tubes
In a LINAC the time is kept constant in the drift tubes by
decreasing the length of the drift tubes
changing the length of the drift tubes
increasing the length of the drift tubes
accelerating the electrons
In a CYCLOTRON the protons are accelerated by
the magnetic field
the magnetic field and the electric field
the electric field
the dees
In a CYCLOTRON the time is kept constant by
the increasing radius of the proton's path
the increasing size of the dees
the electric field
the AC supply
