What Variables Can Be Changed in a Cathode Ray Tube Experiment?

AI Thread Summary
In a discussion about a Year 12 physics EEI using a cathode ray tube (CRT), participants suggest changing the anode voltage and applying various magnitudes of orthogonal magnetic fields to gather data. Concerns are raised regarding the absence of X-ray shielding in the CRT setup. The conversation emphasizes the importance of selecting appropriate accelerating voltages for safe experimentation. Overall, the focus is on identifying manageable variables for effective data collection in the experiment. Understanding these variables is crucial for a successful investigation.

For my year 12 physics EEI (extended experimental investigation) i need to develop some sort of experiment with variables i can change to retrieve data from. I have a basic cathode ray tube from a few months ago much like the one in this video: . Does anyone have any idea of what variables i could change with this experiment? (Sorry for my english. it's my second language)

Thank you

Welcome to the PF.

You can change the anode voltage while applying different magnitudes of orthogonal B-fields across the neck of the CRT...

BTW, what accelerating voltage are you planning on using? That bottle looks to be missing any X-ray shielding...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
