Cards in this deck (11)
- 1Coulomb's Law for ForceF = \(\frac{kqQ}{r^2}\)
- 2Electric Field StrengthE = \(\frac{F}{q}\)
so
F = qE - 3Electric Field Strength: Radial FieldE = \(\frac{kQ}{r^2}\)
- 4Electric Field Strength: Uniform Field (Same Everywhere)E = \(\frac{V}{d}\)
- 5Electric Potential EnergyEp = \(\frac{kQq}{r}\)
- 6Electric PotentialV = \(\frac{kQ}{r}\)
- 7Millikan's Oil-drop Experiment: qE = mgq = \(\frac{mgd}{V}\)
- 8Millikan's Experiment used Stoke's LawF = 6πηrv
mg = 6πηrv
\(\frac{4}{3}\)π\(r^3\)ρg = 6πηrv
----->
\(r^2\) = \(\frac{9ηv}{2ρg}\)
ρ = Density of the oil - 9Current in terms of the velocity of the charge flowing through a wireI = \(\frac{qv}{l}\)
- 10Electromagnetic Force on a wireF = qvB
- 11Particle Centripetal Force: Using Uniform Circular MotionF = \(\frac{mv^2}{r}\)
qvB = \(\frac{mv^2}{r}\)
r = \(\frac{mv}{qB}\)
