Question

An unknown particle is caused to move between two electrically
charged plates, as illustrated in Figure 2.7. You hypothesize
that the particle is a proton. (a) If your hypothesis is
correct, would the particle be deflected in the same or opposite
direction as the β rays? (b) Would it be deflected by a
smaller or larger amount than the β rays?

Which subatomic particle-proton, neutron, or electron-is equivalent to a B ray?
B rays are deflected to a greater extent than a rays because (a) they are lighter,
or (b) they are more highly charged.
Negatively charged B rays bend
toward the positively charged plate.
|(+)
y rays, which carry no charge, are

unaffected by the charged plates.
Positively charged a rays bend
toward the negatively charged
plate.
(-)
