Two identical particles (X and Y) of charge -2.0 pC are suspended from insulating strings attached to the ceiling. 1. Which of the below diagrams (A-E) show the relative positions of the two particles when they are at rest? Select all that apply and explain your reasoning. A B D E 2. Is the magnitude of the electric force experienced by particle X greater than, less than, or equal to the magnitude of the electric force experienced by particle Y? Explain. 3. Draw free-body diagrams for particles X and Y. The lengths of your vector arrows should be qualitatively correct. Identify the type of forces exerted on the particle and label your forces appropriately. 4. What mass would each particle need to have in order for the particles' strings to make angles of 35" with respect to the vertical? Assume the particles are 5.0 cm apart. Show your work. 5. Find the magnitude and direction of the electric field at the location of particle X, and the magnitude and direction of the electric field at the location of particle Y. Show your work. 6. Is there a location at a finite distance from the charges at which the magnitude of the electric field due to both charges is zero? If so, make a sketch to indicate where this occurs (approximately; no calculations are necessary). Explain. Imagine the charge of particle X increases to -6.0 pC, but the charge of particle Y remains -2.0 pC. 7. After the charge of particle X increases to -6.0 pC, is the distance between particles X and Y greater than, less than, or the same as the distance between those two particles when particle X had a charge of -2.0 pC. Explain. 8. Is the magnitude of the electric force experienced by particle X greater than, less than, or equal to the magnitude of the electric force experienced by particle Y? Explain.9. Draw free-body diagrams for particles X and Y. The lengths of your vector arrows should be qualitatively correct. Identify the type of forces exerted on the particle and label your forces appropriately. 10. How does the magnitude of the electric field due to particle Y at X's current location compare to the magnitude of the electric field due to particle X at Y's current location? Explain. 11. Explain how is it possible that particles X and Y can experience electric forces that have the same magnitude while simultaneously experiencing electric fields that have different magnitudes. Imagine that both particle X and particle Y again have the same -2.0 pC charge and particle Z, of charge +2.0 pC, is held at a fixed position midway between X and Y. 12. Is the distance between particles X and Y after particle Z was added greater than, less than, or the same as the distance between particles X and Y before particle Z was added? Explain. 13. Draw free-body diagrams for particles X and Y. The lengths of your vector arrows should be qualitatively correct.
