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.

Score: E-peild Imagine a proton moving initially at 2.1x 10 m/s in the positive direction of the x-axis. It moves in a field-free space until it passes by the origin, x-0, where it encounters an electric field directed along the x-axis. (The y and z components of the field are zero everywhere.)
