Question
see photo,
If a charge q0 travels a distance, d, from point A to point B in a uniform electric field of magnitude E parallel to the field lines, what is the work done by the electric field on the charge? [Notice that if the charge q0 is positive, then the work will be positive , so that charge now has more energy. This energy will be kinetic; the charge will be going faster by the time it reaches point B.] If the charge q0 travels the same distance, d, from point A to point B in a uniform electric field of magnitude E perpendicular to the filed lines, what is the work done by the field on the charge? If the charge q0 travels the same distance, d, from point A to point B in a uniform electric field of magnitude E, and along a path that is tilted at 45 degrees to the field lines, what is the work done by the field on the charge? 3
