The positive and negative plates of a parallel-plate capacitor have an area of 4.30 cm by 4.30 cm. Their surface charge densities are +1.0010^-6 C/m² and -1.0010^-6 C/m², respectively. A proton moving parallel to the plates enters the middle of the space between them at a speed of 7.2010⁶ m/s. Assuming the field outside the capacitor is 0 and the field inside is uniform, how far to the side will the proton's path have deviated when it gets to the far end of the capacitor? PLS I NEED HELP
