Chapter 15, Problem 15.93(choose chapter or problem)
Protons are projected with an initial speed v0 _ 9 550 m/s into a region where a uniform electric fi eld E _ 720 N/C is present (Fig. P15.64). 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 (a) the two projection angles u that will result in a hit and (b) the total duration of fl ight for each of the two trajectories.
