Question

Help me check my answers on electric field physics questions please? Will give medal & fan.

1. Which of the following would be true if a test charge were negative instead of positive?
A. the field lines for negative source charges would point inward
B. the field lines for negative source charges would point outward
C. the field lines would stay exactly the same
D. the field lines would disappear

Not sure about this one at all but maybe A?

(Posting the other problem(s) in the comments)

Answer 1

2. Which statement best describes how you map an electric field?
A. place a test charge at various distances from the source & determine the magnitude of the field at each point
B. know the strength of the electric field at any point and confirm it with a test charge
C. place a negative test charge equal to the positive source at equal points around some circumference around the source charge
D. start with a small test charge and place a source charge around it at various distances to determine the force at each point

For this one maybe A?
