Question

A positively charged particle is placed near an infinitely long straight conductor where there is zero gravity. Then

• A. The charged particle will not move
• B. It will move parallel to the straight conductor
• C. It will move perpendicular to the straight conductor
• D. It will move with constant acceleration

Answer 1

The correct option is A The charged particle will not move

As the charged particle as at rest, no force will act on it due to the magnetic field produced by the conductor at the site of the charge. Hence, it will remain at rest.
