opposite charges attract and like charges repel one another
proton → positively charged → repelled by the negative plate and attracted by the negative plate
An unknown particle is caused to move between two electrically charged plates, as illustrated below.
You hypothesize that the particle is a proton.
You may want to reference (Pages 46 - 49) Section 2.2 while completing this problem.
If your hypothesis is correct, would the particle be deflected in the same or opposite direction as the β rays?
