OK geoffkait, you are either kidding or totally out to lunch. Anybody care to comment on which it might be? Anybody care to make a comment on why tonearms skate? I can't bear it. Somebody out there might even believe him! The tone arm is not subject to centripetal force because it is not moving. If Geoff were sitting on the record spinning with it he would be subjected to centripetal force and who knows, might do him some good. Tonearms skate to the middle of the record. Because the tonearm is offset (bent) friction of the stylus in the groove pulls the arm towards the center causing the stylus to lean on the left channel (inside groove).
This tendency is counteracted by the anti skating device.
This friction also generates thousands of volts of static electricity in just a few minutes. Pulling records in and out of sleeves does not generate static electricity. It is transferred to the sleeve from a hyper charged record and maybe by somebody like geoffkait who is full of static.
