Example Question #1 : Interpreting Electric Charge Diagrams

A charge of unknown value is held in place far from other charges. Its electric field lines and some lines of electric equipotential (V1 and V2) are shown in the diagram.

A second point charge, known to be negative, is placed at point A in the diagram. In which direction will the second, negative charge freely move?

Toward the original charge Q

It will remain stationary

Toward point C

Toward point A
