A charged particle would continue to move with a constant velocity in a region where.

A

`vecE= vec0, vecB ne vec0`

B

`vecE ne vec0, vecB ne vec0`

C

`vecE ne vec0, vecB= vec0`

D

`vecE= vec0, vecB= vec0`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
(A) No force, acts, iv `vec v and vec B` are parallel.
(b) When `vecv, vecE and vecB` are mutually perpendicular `vecv` does not change if `(E)/(B)=v`
(c) Force force `q vecE(ne0), vecv` must change.
(d) No force acts, so `vecv` does not change.
