Protons are projected with an initial speed v0 = 10250 m/s into a region where a uniform electric field E = 670 N/C is present. The protons are to hit a target that lies a horizontal distance of 1.27 mm from the point where the protons are launched.

Find the following:

(a) the two projection angles θ that will result in a hit

1° (smaller)

2° (larger)

(b) the total duration of flight for each of these two trajectories

3 s (smaller)

4 s (larger)
