Two beams of electrons, beam 1 and beam 2, are moving along straight lines perpendicular to the page. We take the page to be the xy-plane. Beam 1 is moving into the page and intersects the page at point (−2, cm, 0 cm). Beam 2 is moving out of the page and intersects the page at point (2, cm, 0 cm). The streams of electrons are otherwise identical, each carrying current of magnitude 2 A. A negatively-charged particle having charge three times that of an electron is at point (x,y) = (0cm,2cm) and has velocity (vx , vy ) = (5 × 103 m/s, −5 × 103 m/s). What is the magnitude and direction of the net magnetic force on the negatively-charged particle due to the pair of electron beams?
