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

straight line

B

a circle

C

an ellipse

D

a hellix

Text Solution

Verified by Experts

The correct Answer is:
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
