Question

Problem with data for try #2: A proton moves 2.00 cm parallel to a uniform electric field of 277 V/m. What potential difference did the proton move through? (Enter the absolute value of AV.) Defined symbols: E electric filed in V/m d distance the proton moves in m The answer is DeltaV potential difference in V Hints: The connection between work and electric potential is important. Remember that for a uniform force (your forces will always be uniform) W-Fd. The work leads to a change in potential energy W-AU qAV. Note how potential energy is related to electric potential! A note on signs: If you move against the direction the force is pushing, the work is negative, the kinetic energy decreases, and the potential energy increases. If you move in the direction the force is pushing, the work is positive, the kinetic energy increases, and the potential energy decrease. (The latter is the case in this problem.)
