It decreases as 1/R3 for large z. Looks like a spring. Problem 76. Calculus gift, sums replaced by integrals. Does an electron oscillate through the center fo the ring", "Image XResolution": "200", "Image YResolution": "200", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
