You cause a particle to move from point A, where the electric potential is 17.5 V, to point B, where the electric potential is -29.5 V. Calculate the change that occurs in the particle's electrostatic potential energy, when the particle is an electron, a proton, a neutral hydrogen atom, and a singly ionized helium atom Gi.e., lacking one electron from its neutral state). electron J proton: neutral hydrogen atom: J singly ionized helium atom:

The differences in electric potential or voltage (we use both terms interchangeably) can be used to determine changes in the electric potential energy of a charged object. If I have a particle with a charge q that is moving between two points in space which have a difference in electric potential (or voltage) of ΔV, the change in electric potential energy of that object is given by ΔEPE = q ΔV. When answering the following questions remember that a gain...
