Electric Fields
... The direction of a field line in the electric field is the direction of the force on a small POSITIVE charge. Thus if a positive charge is placed at a point in a field, it will feel a force in the direction of the field line at that point, but if a negative charge is placed there, it will feel a for ...

It is well known that the screening of purely electric forces is associated with the fact that the external electric field gives rise to charge polarization on a screen and this polarization in turn produces a field that compensates the external one. The described mechanism of screening does not aff ...
