1) A charged particle moves with velocity 1.5 km/s making angle
50° with the external magnetic field of magnitude of 0.6 T (see
figure below). The field exerts the 3.5 N force on the charge. The
direction of the force is out of the page/screen. What is
the magnitude and sign of the charge?
The magnetic force would be zero if:
v was parallel to the field;
v was directed out of page;...
