Two parallel, metal plates with separation distance d = 1.00 cm
carry charges of equal magnitude but opposite sign. The plates are oriented horizontally. Assume the electric field between the plates is uniform, and it has a magnitude of 2,140 N/C. A charged particle with mass 2.00 ✕ 10−16 kg and charge 1.02 ✕ 10−6 C is projected from the center of the bottom negative plate with an initial speed of 1.07 ✕ 105 m/s at an angle of 37.0° above the horizontal. Assume the plates are square with side
length = 20.0 cm.

Where does it strike, relative to its starting point? (Enter the horizontal distance from the initial position, in m. If it does not strike either plate, enter 0.)

What If? What is the minimum initial speed (in m/s) the particle must have in order to change the answer to part (b)?
