Answer:
B. made to bend if it is deflected by encountering a positive charge
Step-by-step explanation:
J J Thomson's experiment is basically related to the discovery of the electron.
Thomson proved from his Cathode ray tube experiment that the cathode ray were actually a stream of electrons. In his Cathode ray tube experiment, he used the fact that the electric force and the magnetic force will be in equilibrium and that in such a situation, the electron does not deflect. He showed that charged particles can be deflected .
