Problem 10: The two charges shown are fixed in place. The positively charged particle has a net charge of 100 nC. The positively charged particle has a net charge of 50 nC. The two charges are 4.0 mm apart. The point indicated is at the midpoint of the two charges. +10000 2.0mm 2.0mm + 4.0mm A. What is the magnitude and direction of the electric field at the point indicated? Describe what this tells value you about that point in space. B. What is the value of the electric potential at the point indicated? Describe what this tells value you about that point in space. C. Imagine that a 3rd particle with a net charge of +10 nC starts very far away and is then brought to the point indicated. How much work was required to bring that 3rd particle to that location? Did this result in a net increase, a net decrease, or not net change to the electric potential energy of the system? D. Now that the particle is being held at that location, how much external force is required to keep the particle remaining at rest at that location? E. If the 3rd particle is let go and free to move, what energy transformations take place? In which direction does the particle initially move?
