The lines in the figure below show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. Note that these are point charges (one is not bigger in size than the others; they're points). That means that the potential goes to infinity as you approach them. We stop showing countours past plus and minus 7kV. The white space is where the potential is greater or less than that. The values of the equipotential lines are in kV, and we labeled the +1, 0, and -1 kV contours. The positions of the charges are also labeled. For the following, check each box that corresponds to a true statement. Select "None of the above" if none of them are true. A. Charge Q3 has the smallest magnitude of all. B. Charge Q1 is a positive charge. C. The magnitude of the electric field at point f is zero. D. The electric field at point e is stronger than the field at point c. E. Charge Q2 is the smallest negative charge. F. The force on a proton at point c would point towards charge Q3.

A. Charge Q3 has the smallest magnitude of all.
B. Charge Q1 is a positive charge.
C. The magnitude of the electric field at point f is zero.
D. The electric field at point e is stronger than the field at point c.
E. Charge Q2 is the smallest negative charge.
F. The force on a proton at point c would point towards charge Q3.
G. None of the above.
I am pretty sure that E is true but I think that there are others that are also true.
