Q.
A charged particle enters a magnetic field $H$ with its initial velocity making an angle of $45{^\circ}$ with $H$. The path of the particle will be
A) A straight line
B) A circle
C) An ellipse
D) A helix
Explanation
(d) 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
