Question
(a) R
(b) R/100
(c) R/1000 from the center of the disk?
(d) Why does the acceleration magnitude increase only slightly as the release point is moved closer to the disk?
(e) Estimate the magnitudes of the electric field for those three distance on the z axis, R, R/100, R/1000.
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 + 4.00 MuC/m^2. What is the magnitude of the electron's initial acceleration if it is released at a distance (a) R (b) R/100 (c) R/1000 from the center of the disk? (d) Why does the acceleration magnitude increase only slightly as the release point is moved closer to the disk? (e) Estimate the magnitudes of the electric field for those three distance on the z axis, R, R/100, R/1000.Explanation / Answer
believe E is;
E = (sigma/2epsilon)(1 - z/SqRt[z^2 + R^2])
The distances they want you to use are up along the z-axis of the disc. So
a)z = R
b)z = R/100
c)z = R/1000
