In a region, steady and uniform electric and magnetic fields are present . These two fields are parallel to each other. A charged particle is released from rest in this region . The path of the particle will be a
A
helix
B
straight line
C
ellipse
D
circle
Text Solution
Verified by Experts
The correct Answer is:
B
The charged particle will move along the lines of electric field ( and magnetic field).Magnetic field will exert no force. The force by electric field will be along the lines of uniform electric field. Hence the particle will move in a straight line.
