The one is at a potential of 5000 V. The other is at a potential of -150 V. Which point has a higher electric field? Explain. Three neutral spherical objects are placed near a positive 10 ,uC point charge. A hollow conductor, a solid conductor, and a solid insulator. How do the fields inside the objects compare? How do the potentials inside the spheres compare? How does the force exerted on the point charge compare? Explain. A charge distribution generates the equipotential lines shown in figure. Rank the corresponding electric field at points A, B, C, and D. Explain your reasoning. How does the work for a positively charged particle going from A to C compare with going from A to D? Explain
