A uniform magnetic field is in the positive z-direction. A positively charged particle is moving in the positive x-direction through the field. The net force on the particle can be made zero by applying an electric field in what direction?
Correct answer: A. Positive y
- A. Positive y
- B. Negative y
- C. Positive x
- D. Negative x
Explanation
F direction= = negative y- direction if electric field is applied in positive y-direction, then Fm = Fe (Fnet = 0)

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
