1. Conceptual question: The picture below shows arrows representing the electric field of a charge particle and three points in space, labeled 1, 2, and 3. 1 (a) At which two points does the electric field have the same strength (magnitude) but different directions? Explain your reasoning. (b) At which two points does the electric field have different strengths (magnitudes), but the same direction? Explain your reasoning. 2. Figure below shows three electric charges, A, B, and C. Their combined electric field is represented by electric field lines. (a) How can you determine the sign of each charge and what is it? (b) How would you determine how the strengths of the electric charges compare? Use that method to rank the charges based on the strength, starting with the strongest first
