# Interpreting Field Line Figures

EANDM-BPIWDF

The figure below shows electric field line drawings for two isolated charges $Q_A$ and $Q_B$. The charges are both part of the same very large field line drawing.

Which of the following conclusions can you make based on these field line figures? Select ALL that apply.

A

Both charges are negative.

B

Both charges are positive.

C

$Q_A = 2 \times Q_B$.

D

$|Q_B| = 2 \times Q_A$.

E

Field line drawings are arbitrary so no conclusion can be made about the relative charges $Q_A$ and $Q_B$.
