Crookes tube experiment with electric field
WebA large transparent Crookes tube, shown in Figure 1, filled with low-pressure hydrogen gas makes a clearly visible beam of electrons, which is shown in Figure 2. The beam is … WebIt says: When only electric field is applied, the electrons deviate from their path and hit the cathode ray tube at point A. Similarly when only magnetic field is applied, electron strikes the cathode ray tube at point C.

Thus, it was proven that the particles were negatively charged. Further experiments helped to prove that the negatively charged particles were actually part of individual atoms, and not a unique particle.
