A particle of mass m=1.6x10^-27kg & charge q=1.6x10^-19C moves @ a speed of 10^7m/s.It enters a region of uniform magnetic field @ point E, as shown in the figure.The field has a strength of 1T.(a)The magnetic field is directed into the plane of paper.The particle leaves the region of the field@ F.Find distance EF and theta.(b)If field is coming out of the paper, find the time spent by the particle in the region of magnetic field after entering it @ E.
