1. The problem statement, all variables and given/known data In the oscilloscope shown, an elctron beam is deflected by an electric force produced by charged metal plates AD and BC. In the region ABCD, each elctron experiences a uniform downward electric force of 3.2x10^-15N. Each electron enters the electric field along the illustrated axis, halfway between A and B, with a velocity of 2.25 x 10^7 m/s parrallel to the plates. The electric force is zero outside ABCD. The mass of an electron is 9.11 x 10^-31 kg. The gravitational force can be neglected during the short time interval an electron travels to the fluorescent screen, S. Determine how far en electron is below the axis of entry when it hits the screen. http://img222.imageshack.us/img222/6886/physicsproblem16mod3xf6.jpg [Broken] 2. Relevant equations 3. The attempt at a solution I really have no idea how to go about this, my classmates and I have been working on it all day, and we don't even know how to go about doing it. Any help is wonderful. And sorry for my paint skills.
