B. Determine the magnetic field (direction and magnitude) that will cause the electron traveling at 3.0 x 105 mfs (the default speed given in the animation) to move clockwise in a circle (in the plane of your paper) of radius 10.0 cm. This is a net force problem i In order to receive credit for the direction of the required magnetic eld, you must show the direction of ALL relevant vectors (velocity, magnetic field. and magnetic force) somewhere in your solution (all in the same place!) along with showing the sign of the moving charge. After you've made your prediction, test it using the animation. Were you correct? If not, find and fix any errors in your prediction. C. What happens to the speed of the particle as it moves? Explain why this happens. cp-mfield-02.iwp A charged particle moves under the influence of a magnetic field oriented along the z-axis (perpendicular to the screen). The direction of positive B is +z (outward from screen). The blue vector on the particle represents its acceleration. The grid scale is located under the tab marked by two boxes.
