An electron e is released from rest on the central axis of, Ask an Expert

Academics

An electron e is released from rest on the central axis of a uniformly charged disk of radius R. The surface charge density on the disk is +4.0(10)^-6 C/m^2. I need the magnitude of the electrons initial acceleration if it is released at distance:

(a) R
(b)R/100
(c)R/1000
from the center of the disk?
And why does the acceleration magnitude increase only slightly as the release point is moved closer to the disk?
