Five equal-mass particles (A–E) enter a region of uniform magnetic field directe

Question

Five equal-mass particles (A–E) 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?

Part B

Which particle (if any) is negatively charged?

Rank the particles on the basis of their speed.

Rank from largest to smallest. To rank items as equivalent, overlap them.

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.

A

B

C

D

E

Part E

Now assume that particles A, B, C, and E all have the same magnitude of electric charge. 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.

E

particle A particle B particle C particle D particle E none A B C D E A BC D E

Explanation / Answer

a) particle D is neutral as it remains undeviated.

b) particle A is negatively charged as it moves in clockwise direction.

c) particle D moves faster than A, which moves faster than B, which moves faster than C and E. because of their greater radius of curvature.

particles E and C move with same speed.

d) same as part (c)

e) Particle A is faster than B, while as the speed of C and E have same speed. Reason same as part(c).
