An ion of mass 6.5x 10 -15 kg and charge of known magnitude q is observed to move in a straight line through a region of space in which a uniform magnetic field of 5.0T points out of the paper and a uniform electric field 2500 N/C points toward the top edge of the paper as shown in the region I in the diagram. The particle travels into region II in which the same magnetic field is present, but the electric field is zero. In region II, the ion moves in a circular path as shown.
a) Indicate and label on the diagram the forces which act on the ion at point P1 in region 1
b) What is the ion's speed v at point P1?
c)Indicate on the diagram the direction of the force on the ion at point P2 in region II
d) Is the ion positively or negatively charged? Explain your reasoning.
