Question

A charged particle enters in a magnetic field H with its initial velocity making an angle of 45° with H. The path of the particle will be (A) an ellipse (B) a straight line (C) a circle (D) a helical

Tardigrade Admin · Accepted Answer

The component of velocity perpendicular to H will make the motion circular while that parallel to H will make it move along a straight line. The two together will make the motion helical.
