Question

Protons are projected with an initial speed v0 = 9,650 m/s into a region where a uniform electric field of magnitude E = 500 N/C is present (see figure below). The protons are to hit a target that lies a horizontal distance of 1.30 mm from the point where the protons are launched.

(a) Find the two projection angles ? that will result in a hit. (Enter the smaller angle first.)
?1 = °
?2 = °

(b) Find the total duration of flight for each of the two trajectories. (Enter the smaller duration of flight first.)
t1 = s
t2 = s
