2.4.1 Logic reexamination on vector field E

Reviewing the whole process to infer the vector field E(x) shown in(2.3.6)from anempirical mechanical formula (2.3.3),which shows the force F acted on a charged particle atposition x by another charged particle elsewhere,we can reasonably predicate both o ......（本文共 1722 字 , 2 张图）     [阅读本文] >>
