Question

Which of the following particles will not be deflected by charged plates?
a. hydrogen atoms
b. cathode rays
c. alpha particles
d. protons
e. These are all deflected by charged plates.

Answer 1

Answer:

oppsion E is correct

Explanation:

beacuse all are dedected by plates

Answer 2

A

Explanation:

 Thomson placed two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles. so cathode rays are excluded

Protons are positively charged and are thus deflected on a curving path towards the negative plate. so also protons are excluded

Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields so alpha rays are excluded
