A charged particle enters a magnetic field H with its initial velocity making an angle of 45∘ with H. The path of the particle will be
A
A straight line
B
A circle
C
An ellipse
D
A helix
Answer
A helix
Explanation
Solution
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.
