一、选择题 1、关于静电场场强的概念,下列说法正确的 是() A.由E二F/q可知,电场中某点的电场强 度与电场力F成正比,与电量q成反比 B.电场中某点的场强方向跟正电荷在该点 的受力方向相同 c.公式E=F/q是电场强度的定义,其中 的E是任意电场中某点的场强,而不限于点电荷 电场的场
First, multiple-choice questions 1. Regarding the concept of field strength of the electrostatic field, the following statement is correct () A. It can be known from E2F/q that the electric field strength at a certain point in the electric field is proportional to the electric field force F and inversely proportional to the electric energy q. B. The direction of the field strength at a certain point in the electric field is the same as the direction of the positive charge at the point. c. The formula E=F/q is the definition of the electric field strength, where E is the field strength at a certain point in any electric field, not Fields confined to point charge electric fields
