-27 A particle of mass m=16x 10kg and charge q= 16 x 10-0 C moves at a speed of 10 x 10' m s. It enters a region of uniform magnetic field at a point E, as shown in figure (34-W4). The field has a strength of 10 T. (a) The magnetic field is directed into the plane of the paper. The particle leaves the region of the field at the point F. Find the distance EF and the angle 8. (b) If the field is coming out of the paper, find the time spent by the particle in the region of the magnetic field after entering it at E. 0. E X X X X Figure 34-W4 X X X
