Homework Help: Electric potential

  1. Jul 5, 2009 #1
    1. The problem statement, all variables and given/known data
    A proton is released from rest in a uniform electric field of magnitude 1.8*10^5 V/m directed along the positive x axis. The proton undergoes a displacement of 0.6 m from the positively charged end of the field to the negatively charged end of the field. (a) Find the change in the electric potential if the proton moves from point A to point B. Answer in units of V. (b) Find the change in potential energy of the proton for this displacement. Answer in units of J. (c) Apply the principle of energy conservation to find the speed of the proton after it has moved 0.6 m, starting from rest. Answer in units of m/s.
