Electric Potential Energy Chapter 20 Electric Potential and
physics.gsu.edua) A positive test charge q 0 experiences a downward force due to the electric field E. If the charge is moved upward a distance d the work done by the electric field is -(q 0)Ed. At the same time, the electric potential energy of the system increases by (q 0)Ed. The situation is analogous to that of an object in a gravitational field. (b) If a

physics.ucf.eduMeasuring Magnetic Fields with Test Charges - In general, if a magnetic field (B) is present, the electron beam is deflected. However this is not true if the beam is // to B ( φ= 0, π F=0 no deflection). Ex: electron beam in a cathode X-ray tube. No deflection F = 0 v // B Deflection F ≠0 F ┴v, B Electron q< 0 F has contrary
