Chapter 17 Flashcards
What is charge measured in?
Coulombs
What do you need to model something like a “Point Charge”?
Sphere with evenly distributed charge.
What is Coulomb’s law used for?
Calculating the forces (Attraction or Repulsion) between two point charges.
What is Electric Field Strength?
Force per Unit Charge.
What is the relationship between Eelectric and r² in a radial field?
Inversely proportional.
What kind of potential energy does a charge in an electric field have?
Electric potential energy.
What is electric potential?
Potential energy per unit charge.
What law did Millikan’s oil drop experiment use?
Stoke’s Law.
What is Stoke’s Law?
F(drag through a viscous fluid)=6πηrv
Felectric(for radial components)=
kqQ/r²
Eelectric(for radial components)=
Felectric/q
Eelectric(for a uniform field)=
V/d
F(charged particle in magnetic fields)=
qvB
F(uniform circular motion)
mv²/r
