A particle of mass M and positive charge Q moving with a constant velocity v=4m/s, enter a region of uniform static magnetic field normal to the x-y plane. The region of the magnetic field extends from x=0 to x=L for all values of y. After passing through this region, the particle emerges on the other side after 10 msec with velocity v=w[SQRT(3)i+j]m/s. The correct statement(s) is (are):
A) The direction of the magnetic field is -z direction.
B) The direction of the magnetic field is +z direction.
C) The magnitude of the magnetic field is [50(pi)M/(3Q)].
D) The magnitude of the magnetic field is [100(pi)M/(3Q)].
