I Review I Constants A parallel-plate capacitor has 3.9 cm x 3.9 cm electrodes with surface charge densities +1.0 x 10-6 C/m?.A proton the electrodes at 1.9x106 m/s enters the traveling parallel center of the gap between them. Part A uniform inside the capacitor By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field and zero outside the capacitor. Express your answer to two significant figures and include the appropriate units.
