Question

Review I Constants I Periodic Table Learning Goal A vertical wire caries current in the upward direction. An electran is traveing parallel to the wire. What is the angle a between the velocity of the electron and the magnetic field of the wire? To practice Tactics Box 24.2 Detemining the magnetc force on a moving charged particla Express your answer in degrees. When a particle of charge g moves with a velocity in amagnetic field B, the particle is acted upon by a force Rexerted by the magnetc field. To find the direction and magnitude of this force, follow the stepe in the following Tactics Box, Kaep in mind that the right-hand nie tor torces shown in step 2 gvas the direction of the force on a positive charge. For a negative charge, the force will View Available Hintis) be in the opposte drection degres Submit Part B In what direction is the torce Pexerted by the magnetic field on the electron? Fis parallel to the wire and points upward. Fis parallel to the wire and paints dawnward Fis perpendicular to the wire and points taward the wire.
