1. A proton is placed at point A, where the electric potential is 200 V . The proton is released from rest. Some time later, the proton has reached point B, where the electric potential is -120 V . What is the de Broglie wavelength of the proton when it reaches point B? 2.We then place an electron at point B and release it from rest. What is its de Broglie wavelength when it reaches point A?
A proton is released from rest at point A in a constant electric field and accelerates to point B (see part a of the drawing). An electron is released from rest at point 8 and accelerates to point A (see part b of the drawing). How does the change in the proton's electric potential energy compare with the change in the electrons electric potential energy? O The proton experiences a greater change in electric potential energy, since it has a...
A proton and an electron are separately placed at rest in the same uniform electric field. What can be said about the energy of each after they are released? A) Electric potential energy of both decreases, and kinetic energy of both increases. B) Electric potential energy of both increases and kinetic energy of both decreases. C) Electric potential energy and kinetic energy of both remain constant. D) Electron potential energy increases, proton potential energy decreases. E) Electron potential energy decreases,...

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:
