When a charged particle is projected perpendicular to a magnetic field:
Correct answer: A. It's path is circular in a plane perpendicular to the plane of the magnetic field
- A. It's path is circular in a plane perpendicular to the plane of the magnetic field
- B. The speed and kinetic energy of the particle do not remain constant
- C. The velocity and momentum of the particle change in direction and magnitude
- D. The time period of revolution, angular frequency, and frequency of revolution are independent of the path of the particle and radius of the circular path
Explanation
A charged particle moving perpendicular to the field experiences a force always prependicular to it's motion causing it to move in a circular path. It's speed remains constant so motion is uniform circular motion in plane prependicular to the field.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
