Start Quiz
1.
In a velocity selector with perpendicular E and B the speed of undeflected particles is
EB
E/B
B/E
E2/B
2.
The undeflected speed in a selector depends on the particle's
charge only
mass only
neither charge nor mass
both charge and mass
3.
For E = 2000 V m−1 and B = 0.050 T the selected speed is
1.0 × 102 m s−1
2.5 × 10−5 m s−1
4.0 × 104 m s−1
1.0 × 105 m s−1
4.
A particle faster than the selected speed in the selector is deflected because
the magnetic force exceeds the electric force
the electric force exceeds the magnetic force
the magnetic force is zero
gravity dominates
5.
Thomson's experiment determined
the charge of the electron
the mass of the proton
the mass of the electron alone
the charge-to-mass ratio of the electron
6.
After a velocity selector, ions of the same speed and charge enter a magnetic field only. The ion with the largest mass
follows the smallest radius
follows the largest radius
is undeflected
follows a straight line
