Cathode Rays Are Deflected Away From A Negatively Charged Plate Because

When a cathode ray is passed through this electric field, the negatively charged electrons are deflected toward the positive charged plate and away from the negatively charged plate. Are cathode rays negatively charged? Cathode rays travel in straight lines and cast sharp shadows. Because a cathode ray deflected away from a negatively charged plate and towards a positively charged one, scientists concluded that a.
