In Fig. an electron (e) is to be released from rest on the central axis of a uniformly chargeddisk of radius R. The surface charge density on the disk is +5.00 mu C//m^(2). What is the magnitude of the electron's initial acceleration if it is released at a distance (a) R, (b) R/100, and (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 ? |
| Answer» Solution :(a) `1.45 xx 10^(16) m//s^(2)`, (B) `4.93 xx 10^(16) m//s^(2)`, (c ) `4.96 xx 10^(16) m//s^(2)` | |
