Charged particles each enter a region of constant magnetic field that points into the page. Each charge enters with the same velocity. Particle 1 moves counterclockwise in a small circular orbit. Particle 2 moves in a much wider circular orbit as shown. Particle 3 moves straight through the magnetic field. Particle 4 moves in a small circle with the same radius as particle 1 but orbits clockwise. Identify each particle as gamma ray, alpha, beta-plus, or beta-minus.
