part A) A proton begins at the negative plate of a parallel plate capacitor. The plates are separated by 12 cm and generate a constant electric field of 3,283 N/C directed from the positive plate to the negative plate. The proton is "launched" with an initial velocity of 5 x 105 m/s at an angle of 30o from the horizontal. What is the maximum height that the proton achieves above the negative plate before falling back down? Express your answer in centimeters.
