Answer 1

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

Those are the anwser choices

Answer 2

The density of field lines on a source charge indicates the strength of the charge there is. The field lines all represent the movements of field charges. Naturally, if there are a large number of them compressed in an area, then that would mean the charge at that certain point is strong
