Homework Statement
I'm making a ball cyclotron (https://rimstar.org/science_electronics_projects/ball_cyclotron_electrostatic_accelerator.htm) for a school project. To generate enough voltage, I'm using a Van der Graaf-generator. The problem is that all the voltage, which I can measure...
So, there will be a component parallel to the velocity and the radius of the circle would grow over time. How could I, practically create something like that?
Homework Statement
As you'll know, the driving force for a circular movement is a centripetal force. But wat is the dynamics for a spiral movement, i.e. an increasing circular movement? And how can I produce it, let's say for a little spherical object, in real life?
