Hi, Could you please help me solve this question? The details are in the picture below.

The positive and negative plates of a parallel-plate capacitor have an area of 1.15 cm by 1.15 cm. Their surface charge densities are +1.00x10-6 C/m2 and -1.00x10-6 C/m2, respectively. A proton moving parallel to the plates enters the middle of the space between them at a speed of 8.10x10 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
