(4) upward
A positively charged particle (alpha particle), projected towards west, is deflected towards north by a magnetic field. The direction of magnetic field is
(1) towards south
(2) towards east
(3) downward
(4) upward
solution:
By applying Fleming’s left hand rule, we find that the magnetic field is in upward direction. Thus, option
(4) is correct.
