As the filament temperature through it (a voltage of 6.3 volts for the req is are released from its surface with almost zero e apply a high voltage V (150-300 volts) to 2 parallel Plates in the small region where electrons are created.

The Fa points inward due to the right hand rule. equal toeV ergy ofthe electrons (charge e) in this potential Δν is provides the kinetic energy for the electrons to a velocity v from the negative side to the posiive of the plates combination. A magnetic field B perpen electron velocity vector is present and field experienced by the electrons is parallel to the axis and its strength is proportional to the current in the co ndicular to it acts on the. The magnetic of two coils ils. As elect rons move they collide with helium gas atoms inside the b and cause the gas to glow, making the beam path visible. Writeabout: In your notebook, construct an argument explaining why you see a glowing circle in the bulb during the demo. Here are a few questions to help you, but feel free to share your own ideas to0. Draw a sketch of the demo apparatus (i.e. a large bulb, the stream see how to represent magnetic fields graphically). Don't forget to b. Draw a Force Diagram for the a single electron at multiple points с.write out analgebraie representation of the Net Force on a single field? What do you know about particles that travel with constant a. of electrons, and the external magnetic field. See Figures 1 and 2 to explain using the Right Hand Rule on its trajectory. What do you notice? Figure 2: a graphical representation of a electron. What is the definition of Fe for a charge in an external egatively charged particle speed in a perfect circle? with velocity v in an extern magnetic field Bin, which points into the page.
