Unformatted text preview: F qE F Hq W AB = F E x D W AB = qED W AB = F Hq x D B A What is the change in potential energy in going from A to B? F qE F Hq W AB = qED PE AB = qED PE AB = q V AB V AB = ED AB W AB = qED Only applies when the field is uniform over the distance. V AB s sign depends on the direction of E. In this case its positive....
