A parallel-plate capacitor has 2.8cm � 2.8cm electrodes with surface charge densities �1.0�10?6C/m2. A proton traveling parallel to the electrodes at 1.0�106m/s enters the center of the gap between them.
By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor.
Express your answer to two significant figures and include the appropriate units.
