Answers
Answers: 1
A particle of mass M and positive charge Q, moving with a constant velocity u⃗ 1=4i^ ms−1 enters 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 milliseconds with a velocity u^2=2(3i^−−√+j^)ms−1. 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 50πM3Q units
(D) The magnitude of the magnetic field 100πM3Qunits.
