UCF PHY2054 Post Lab - Unit 04 Relating Field to Equipotential Lines Consider this field to be an electric field produced by a negatively charged sphere. Recall that an equipotential line consists of points that all have the same potential. So, when a charge moves along an equipotential line, it neither gains nor loses potential energy. Draw the equipotential line through point G, making sure it contains all 1. points on the page that have the same potential as G. Explain your reasoning. Draw the equipotential line through point H. 2. Censide lectric fold INIA PIN VICTORIAS S
