Location D is 0.06 m from the sphere. What is the change in potential along a path from C to D ? V = -1200 -1200 V 2. 4/4 points Question: MI3 17.5.X.059 Locations A and B are on the +x-axis. A is at location < a, 0, 0>, and B is at location < b, 0, 0>. In the columns below, the left-hand column contains possible expressions for the electric field at locations along the +x axis, and the right-hand column contains possible expressions for the potential difference V A - V B . For each expression for electric field along the x axis, choose the correct expression for the potential difference V A - V B . 7
