The number of electric field lines passing through a unit cross-sectional area is indicative of
A)field direction.
B)charge density.
C)field strength.
D)charge motion.

Question

Quizplus · Accepted Answer

The number of electric field lines passing through a unit cross-sectional area is indicative of the field strength. The greater the number of field lines, the stronger the electric field. The direction of the field can be determined by observing the direction of the field lines, but it is not directly related to the number of field lines passing through a unit cross-sectional area. Charge density and charge motion are not directly related to the number of field lines passing through a unit cross-sectional area.
