Question

multiple choice 1 point
in the cathode ray tube experiment performed by thomson, he observed that placing metals that had a positive or negative charge caused the cathode beam to deflect as seen in the following diagram which, for illustration purposes, has two red electrodes near the cathode ray, one is negative, the other positive.
this information helped to determine the charge of the electron to be____.
negative
positive
neutral
double

Explanation:

In Thomson's cathode - ray tube experiment, electrons are negatively charged particles. When electric fields (created by positive and negative electrodes) are applied, the deflection of the cathode - ray (which is composed of electrons) towards the positive electrode shows that electrons are negatively charged. Opposite charges attract, so the negatively charged electrons are attracted to the positive electrode.

Answer:

negative
