The friends now consider a charged particle with charge q that moves in a region containing a uniform electric field, E, similar to what they've observed in the simulation. They let the length of the plates creating the uniform electric field be L, and the distance between the plates be d. Alston challenges Thana to calculate the maximum speed, v, the charged particle could be moving if it enters the space halfway between and parallel to the two plates and just barely manages to strike one of the plates. Which response is correct?
