Thomson and Millikan's Experiments (HSC SSCE Physics): Flashcards

Charge-to-mass ratio ($\frac{q}{m}$)

$v = \frac{E}{B}$

$\frac{q}{m} = \frac{E}{rB^2}$

They are particles (electrons), not waves

Elementary charge (fundamental unit of electric charge)

$1.6 \times 10^{-19}$ C

Charge is quantised (exists in integer multiples of $e$)

$9.1 \times 10^{-31}$ kg

Crossed electric and magnetic fields

$q = \frac{mgd}{V}$
