Protons are projected with an initial speed v, -9.65 km/s from a field-free region through a plane and into a region where a uniform electric field E-720) N/C
is present above the plane as shown in in the figure below. The initial velocity vector of the protons makes an angle with the plane. The protons are to hit a
target that lies at a horizontal distance of R 1.22 mm from the point where the protons cross the plane and enter the electric field. We wish to find the angle at
which the protons must pass through the plane to strike the target.
