There is found to be a radial electrostatic field (径向静电场) near the earth’s surface.
举一反三
- On the ideal conductor surface, the relationship between the electric field lines and the conductor surface is A: the electric field lines is always pertendicular to the conductor surface. B: the electric field lines is always parallel to the conductor surface. C: there is no electri field lines exsited. D: unable to determine the relationship.
- _____ is covered with heavy snow. A: The earth’s surface B: The surface of earth C: The surface earth D: The earth surface
- ______ is covered with heavy snow. A: The surface of earth B: The earth’s surface C: The earths’ surface D: The surface
- An example of this is motion parallel to the earth’s surface.
- Water (cover) most of the earth’s surface.
