Charged Particles Moving in a Magnetic Field Ranking Task

Five equal-mass particles (AE) enter a region of uniform magnetic field directed into the page. They follow the trajectories illustrated in the figure. (Figure 1)

Part A

Which particle (if any) is neutral?

a) particle A

b) particle B

c) particle C

d) particle D

e) particle E

f) none

Part B

Which particle (if any) is negatively charged?

a) particle A

b) particle B

c) particle C

d) particle D

e) particle E

f) none

Part D Rank the particles A, B, C, and E on the basis of their speed. Rank from largest to smallest. To rank items as equivalent, overlap them.
