A proton moving with speed v = 2.0 X 105 m/s in a field-free region abruptly enters an essentially uniform magnetic field B = 0.850 T (B ┴ v). If the proton enters the magnetic field region at a 45o angle as shown in Fig. 20-53,
(a) At what angle do i leave?
(b) At what distance x does it exit the field?
