[translate] aIn the presence of an electric field and an appropriate solvent,these free charges are forced to migrate in the direction of the electric field 在一个电场和一种适当的溶剂面前,这些自由电荷被迫朝电场的方向移居[translate]
How is the direction of an electric field defined? A field is not a vector, so it does not have a direction. The direction of the field is the direction of the force on a neutron. The direction of the field is the direction of the forc...
In an electromagnetic field, the direction of the magnetic field is perpendicular to the direction of the electric field. If the electric field points north, the magnetic field cannot point ___. A. east B. south C. west D. north 相关知识点: 试题...
directionline of chargeThis article presents that the direction of the electric field of the uniform line of charge can be shown as geometrical rule. We investigate this rule for finite line, semi-infinite line and infinite line. This subject shows compatibility of geometry andphysics.Mehdi Jafari...
40 The diagram below shows a positive charge travelling towards an electric field.本个direction of electric field What is the direction the positive charge will move when it first enters the electric field? C A into the paper B out of the paper C upwards Ddownwards ...
A. Against the direction of the electric field B. In a direction perpendicular to the electric field C. In the same direction as the electric field D. It will not move at all 相关知识点: 试题来源: 解析 C。解析:在均匀电场中,正电荷受到电场力的方向与电场方向相同,所以正电荷会沿着电场方向...
