A proton travels in the x direction and enters a region where a constant uniform electric field is directed in the y direction. Derive an equation which describes the x and y cooedinates of the proton in the field as a function of time t.
The x component of velocity will remain unchanged.
The y component of velocity will start at zero and then accelerate at a rate eE/m in the -y direction. E is the electric field. e and m are the electron charege and mass.
The x and y coordinates are the integrals of the corresponding V coordinates.
You should be able to take it from there.
