A charged particle moves with some initial velocity along the direction of external magnetic field B. Now, If we apply uniform field perpendicular to the magnetic field, then the trajectory of the charged particle will be

A

circle

B

helix

C

cycloid

D

straight line

Text Solution

Verified by Experts

The correct Answer is:
B
As charged particle enters region of electric field, its. net velocity is inclined at some angle to B.

So, path of charged particle is a helix.
