Question
A charge particle is released from rest in a region of steady and uniform electric amd magnetic fields which are parallel to each other. The particle will will move in a
Options
A.straight line
B.circle
C.helix
D.cycloid
Solution
The charged particle will be accelerated parallel (if it is a positive charge) or antiparllel (if it is a negative charge) to the electric field, i.e., the charged particle will move parallel or antiparallel to electric and magnetic field. Therefore, net magnetic force on it will be zero and its path will be straight line.
