1. Which of the following would be true if a test charge were negative instead of positive?
   

Athe field lines for negative source charges would point inward

Bthe field lines for negative source charges would point outward

Cthe field lines would stay exactly the same

Dthe field lines would disappear

1. Which statement best describes how you map an electric field?
   

Aplace a test charge at various distances from the source & determine the magnitude of the field at each point

Bknow the strength of the electric field at any point and confirm it with a test charge

Cplace a negative test charge equal to the positive source at equal points around some circumference around the source charge

Dstart with a small test charge and place a source charge around it at various distances to determine the force at each point
