Which type of field is present near a moving electric charge?
Correct answer: C. Both magnetic and electric field
- A. An electric field only
- B. A magnetic field only
- C. Both magnetic and electric field
- D. Magnetic and gravitational field
Explanation
Magnetic and gravitational field: This option is incorrect. A moving electric charge does not generate a gravitational field. The gravitational field is associated with mass, not electric charge. Therefore, the correct option is "Both magnetic and electric field" as a moving electric charge generates both types of fields in its vicinity.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
