What does the number, or density, of field lines on a source charge indicate?

A.

direction of charge on the source charge

B.

amount of charge on the test charge

C.

amount of charge on the source charge

D.

direction of charge on the test charge

Hello.

The answer: C. amount of charge on the source charge

The field lines all represent the movements of field charges. The more crowded the field lines or the more density of electric field the higher is the magnitude of the source charge.

Have a nice day.
