In the figure an electron (e) is to be released from rest on the central axis of a uniformly charged disk of radius R. The surface charge density on the disk is +4.27 C/m. What is the magnitude of the electron's initial acceleration if it is released at a distance (a) R, (b) R/130, and (c) R/1320 from the center of the disk?
