**Unformatted text preview: **reversed from those given in part (a) . 19.3 Since the particle is positively charged, use the right hand rule. In this case, start with the fingers of the right hand in the direction of v G and the thumb pointing in the direction of G . As you start closing the hand, the fingers point in the direction of B F G after they have moved 90. The results are (a) into th age e p (b) towar (c) d the right t oward bottom of page 19.4 Hold the right hand with the fingers in the direction of v G so that as you close your hand, the fingers move toward the direction of B G . The thumb will point in the direction of the force (and hence the deflection) if the particle has a positive charge. The results are (a) toward top of page (b) out of e page th , since the charge is negative. (c) zero force (d) i nto the page...
