Question

A charged particle moves in a gravity free space without change in velocity. Which of the following is not possible in that space? (A) E=0, B=0 (B) E ≠ 0, B=0 (C) E=0, B ≠ 0 (D) E ≠ 0, B ≠ 0

If vecE ≠ 0 and vecB ≠ 0, vecE will definitely deflect / increase / decrease velocity of charge. If both vecE and vecB are non zero, they may balance each other.

Q. A charged particle moves in a gravity free space without change in velocity. Which of the following is not possible in that space?

$E = 0, B = 0$

$E \neq = 0, B = 0$

$E = 0, B \neq = 0$

$E \neq = 0, B \neq = 0$

If $E \neq = 0$ and $B \neq = 0, E$ will definitely deflect / increase / decrease velocity of charge. If both $E$ and $B$ are non zero, they may balance each other.

Q. A charged particle moves in a gravity free space without change in velocity. Which of the following is not possible in that space?

E=0,B=0

E=0,B=0

E=0,B=0

E=0,B=0

If E=0 and B=0,E will definitely deflect / increase / decrease velocity of charge. If both E and B are non zero, they may balance each other.

$E = 0, B = 0$

$E \neq = 0, B = 0$

$E = 0, B \neq = 0$

$E \neq = 0, B \neq = 0$

If $E \neq = 0$ and $B \neq = 0, E$ will definitely deflect / increase / decrease velocity of charge. If both $E$ and $B$ are non zero, they may balance each other.
