Review I Constants TACTICS BOX 26 3 Right-hand rule for forces Learning Goal: To practice Tactics Box 26.3 Right-hand rule for forces. 1. Spread the fingers of your right hand so that your middle finger is perpendicular to your palm. 2. Rotate your hand until your thumb points in the direction of v and your index finger points in the direction of B.(Eloure 1) 3. Your middle finger now points in the direction of the force F on a positive charge. The force on a negative charge points in the opposite direction. When a particle of charge q moves with a velocity i in a magnetic fleld B. the particle is acted upon by a force F exerted by the magnetic field. To find the direction and magnitude of this force, follow the steps in the following Tactics Box. Keep in mind that the right-hand rule for forces shown in step 2 gives the direction of the force on a positive charge. For a negative charge, the force will be in the opposite direction.
