[Solved] Electric Potential Differences When an electron moves from A to B along an electric field line in Fig. 25-26, the electric field does 2.44*10^-19 J of work on it. http://tinyurl.com/2s34zk Find the electric potential differences from VB->VA and VC->VA. I think the potential difference is the same for each but I'm not positive. I'm not sure what formula to use either...V2-V1= -Welec / q or V2-V1= - integral E*ds ??? If someone could get me started in the right direction I think I can figure out the rest. Thanks for your help!
