Static Electricity Quiz

In a television set with a cathode ray tube display, a beam of negatively charged particles called cathodes rays passes by a positively charged plate. The beam is deflected before it hits the television screen to produce an image. Which of the following changes would result in the greatest increase in the attraction between the negatively charged particles in the beam and the positively charged plate?

• increasing the distances between the plate and the particles and increasing the charge on the plate

• increasing the distances between the plate and the particles and decreasing the charge on the plate

• decreasing the distances between the plate and the particles and increasing the charge on the plate

• decreasing the distances between the plate and the particles and decreasing the charge on the plate
