Four charged particles are fired with a horizontal initial velocity \(\vec{v}_{i}\) into a uniform electric field that is directed vertically downward. The effect of gravity is negligible. The particles have the following charges and masses: particle 1 \((+q, m) ; 2(+q, 2 m) ; 3(+2 q, 2 m) ; 4(-q, m)\). Sketch the four trajectories.
