| Professor Barry Wellman of the University of Toronto in Canada has invented a term t o describe the way many North Americans interact (互动) these days. The 1 is "networked individualism". This concept is not 2 to understand because the words seem to have opposite meanings. How can we be individuals and be networked 3 ? You need other people for 4 . Here is 5 Professor Wellman means. 6 the invention of the Internet and e mail, our social networks included 7 interactions with relatives, neighbors and colleagues at work. Some of the 8 was by phone, but it was still voice to voice, person to person, in 9 time. A recent 10 by the Pew Internet and American Life Project 11 that for a lot of people, electronic interaction through the computer has 12 the person-to-person interaction. However, a lot of people interviewed for the Pew's study 13 that's a good thing. Why? In the past, many people were 14 that the Internet isolated (隔离,孤立) us and caused us to 15 too much time in the imaginary world of the computer. But the Pew's study discovered that the 16 is true.

如图所示，固定于同一条竖直线上的A、B是两个带等量异种电荷的点电荷，电荷量分别为＋Q和－Q，A、B相距为2d。MN是竖直放置的光滑绝缘细杆，另有一个穿过细杆的带电小球p，质量为m、电荷量为＋q(可视为点电荷，不影响电场的分布)，现将小球p从与点电荷A等高的C处由静止开始释放，小球p向下运动到距C点距离为d的O点时，速度为v。已知MN与AB之间的距离为d，静电力常量为k，重力加速度为g。求：
(1)C、O间的电势差UCO；
(2)O点处的电场强度E的大小及小球p经过O点时的加速度；
(3)小球p经过与点电荷B等高的D点时的速度。
