WBJEE · Physics · Magnetic Effects of Current
If \(E\) and \(B\) are the magnitudes of electric and magnetic fields respectively in some region of space, then the possibilities for which a charged particle may move in that space with a uniform velocity of magnitude \(v\) are
- A \(E=v B\)
- B \(E \neq 0, B=0\)
- C \(E=0, B \neq 0\)
- D \(E \neq 0, B \neq 0\)
Answer & Solution
Correct Answer
(D) \(E \neq 0, B \neq 0\)
Step-by-step Solution
Detailed explanation
The charged particle will move with uniform velocity in that space if \(E=0\) and \(B \neq 0,\) since a moving charge in a magnetic field experience a force. Also if \(E = 0, B \neq 0,\) the charged particle will move with uniform velocity in that space. If \(E=v B\), then…
