1. Figure 16-50 shows electric field lines due to a point charge. What can you say about the field at point 1 compared with the field at point 2?
(a) The field at point 2 is larger, because point 2 is on a field line.
(b) The field at point 1 is larger, because point 1 is not on a field line.
(c) The field at point 1 is zero, because point 1 is not on a field line.
(d) The field at point 1 is larger, because the field lines are closer together in that region.

2. A negative point charge is in an electric field created by a positive point charge. Which of the following is true?
(a) The field points toward the positive charge, and the force on the negative charge is in the same direction as the field.
(b) The field points toward the positive charge, and the force on the negative charge is in the opposite direction to the field.
(c) The field points away from the positive charge, and the force on the negative charge is in the same direction as the field.
(d) The field points away from the positive charge, and the force on the negative charge is in the opposite direction to the field.
