Physics 40S RRSD Final Exam – June 2005 Page 830. In the diagram below, proton p, neutron n, and electron e are located as shownbetween two oppositely charged plates (exclude the force of gravity).The magnitude of acceleration will be greatest for thea) neutron, because it has the greatest massb) neutron, because it is neutralc) electron, because it has the smallest massd) proton, because it is farthest from the negative plate31. Electric Field lines are drawn:a) From positive to negative charges with a decreasing number of linesindicating a stronger electric field.b) From negative to positive charges with an increasing number of linesindicating a stronger electric field.c) From positive to negative with an increasing number of lines indicating astronger electric field.d) From negative to positive with a decreasing number of lines indicating aweaker electric field.32. Which of the following diagrams best shows the orientation for a set of fourcompasses placed around a current-carrying wire?
