The tone arm is not subject to centripetal force because it is not moving.If your pickup arm is not moving, then static charges are the least of your worries.
Why does a tonearm skate? ... What does geometry have to do with it? VTF maybe.Geometry has everything to do with skating forces. For example, a linear tangential tracking arm suffers from no skating force at all. What exactly do you think accounts for that as compared to a pivoted arm?
