A charge is moving with velocity v, it enters a uniform electric field E. The direction of v and E are not parallel. What is the path of the charged particle inside the electric field?
Correct answer: A. Parabolic
- A. Parabolic
- B. Circular
- C. Parallel to v
- D. Parallel to E
Explanation
As v and E are not parallel so v and e must be perpendicular. When a charged particle enters an electric field with velocity v, it follows a parabolic path.

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.
