Question

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

Hint:

When the electric and magnetic fields are parallel, the forces act in the same direction, leading to straight-line motion of the particle.

Answer 1

The Correct Option is B

Step 1: If the electric and magnetic fields are parallel, the force on the charged particle due to the electric field will be in the same direction as the magnetic force. 
Step 2: Since both forces act in the same direction, the charged particle will experience a uniform force, causing it to accelerate in a straight line.
