MCQ

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
Circle
B
Helix
✓
Straight line
D
Ellipse

✓

Answer

Correct option: C.

Straight line

c
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
