Recap:
Coulomb’s law states that the force between two charged objects will __________ when the magnitude of the object’s charge increases.
Coulomb’s law also states that the force between two charged objects will __________ when the distance between objects increases.
increase; increase
increase; decrease
decrease; increase
decrease; decrease
Coulomb’s law states that the force between two charged objects will __________ when the magnitude (value) of the object’s charge increases.
increase
decrease
stay the same
first increase, then decrease
The variable "r" in Coulomb's Law would have what units?
Joules
Coulombs
Newtons
Meters
What does "r" measure?
the distance between the two charged objects
the amount of charge carried by the objects
the amount of force between two charged objects
the constant value for forces between the objects
What does Fe stand for?
the electrostatic force
the symbol for iron
the constant for the charges
the charges of the particles
What will be the units of F (or Fe)?
Newtons
Meters
Coulombs
Joules
What does q measure?
the distance between the two charged objects
the amount of charge carried by the object
the amount of force between two charged objects
Why are there two q's in the equation?
because there are two charged objects
because there are protons and electrons
because the particles are moving away from each other
because the particles are moving towards each other
What can you do to increase the value of k?
increase the force
increase the distance
decrease the charge
nothing can be done to change the value of k; it is a constant
Which is the value of the constant in Coulomb's equation?
k = 9·10-9
k = 9.8
k = 6.67·10-11
k = 9 ·109
The law, governing the force between electric charges is known as
Ampere's law
Ohm's law
Coulomb's law
Faraday's law
If the amount of charge increases, the force...
stays the same
gets weaker
gets stonger
turns into soup
As electric charges get closer together, the force between them...
becomes weaker
becomes stronger
stays the same
disapears
If the amount of charge decreases, the force...
fluctuates wildly
stays the same
gets weaker
gets stronger
What variable is used to denote "charge"?
k
q
r
e
What is the standard unit for charge?
Newtons (N)
Coulombs (C)
Electros (e)
Protos (P)
What does the "k" represent in Coulomb's Law?
charge
Coulomb's Constant
kilometers
distance between charges
