When an electron moves from A to B along an electric field line in the figure, the electric field does 4.52 × 10-19 J of work on it. What are the electric potential differences (a)VB-VA. (b)VC-VA, and (c)VC-VB? Electric field line Equipotentials

An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 1.5 cm, and the electric field within the capacitor has a magnitude of 2.5 x 106 V/m. What is the kinetic energy of the electron just as it reaches the positive plate? KE positive = i -Electric field Electron

Question 2: #72    a.  What is the electric potential at point A in Figure below? b. What is the potential energy of a proton at point A?

The figure below shows a region of space with an electric field. The dashed lines indicate equipotential surfaces. A particle with a charge of +5.0x10-6 C is moved from point A to point B at constant speed. (You may assume point A falls exactly halfway between the two nearest equipotential surfaces and that there is no gravitational force). Draw an energy bar chart showing how the energy in the system consisting of the charged particle and the electric field changes as the particle is moved from position A to position B.

The figure by James Clerk Maxwell shows the electric field lines and equipotentials of a pair of positive charges. Charge A has four times the magnitude of charge B. Assume the electric potential is zero infinitely far from the charge configuration. At which point would a negative charge have the greatest electric potential energy? 6 8 If a positive charge has a velocity at point 8, moving to which point would result in the greatest kinetic energy loss? 2 A moving charged particle would experience no net change in kinetic energy when moving between which pairs of points? and 6 4 2 and 4 3 and 7 6 and 8 2 and 8 2 Lines of Force and Equipotential Surfaces.

A proton moves parallel to an electric field between points A and B. The change in the proton's electric potential energy is EPEB – EPEA. If the proton is removed from point B and replaced with an electron, how does the change in electric potential energy of the electron compare to the change in electric potential energy of the proton as the electron moves from point B to point A?
