An electron is released from rest in a region of uniform electric and magnetic fields acting parallel to each other. The electron will
Option: 1 move in a straight line.
Option: 2 move in a circle.
Option: 3 remain stationary.
Option: 4 move in a helical path.
Force due to the electric field will make the charged particle released from rest to move in the straight line
Force due to the magnetic field =qvBsin0=0
Since the force due to the magnetic field is zero, therefore, the charged particle will move in a straight line.
