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 charge particle inside the electric field?
Correct answer: A. parabolic
- A. parabolic
- B. circular
- C. parallel to v
- D. parallel to E
Explanation
In an electric field charged particles move in a parabola - the shape a projectile follows. This is because the force always acts in the same direction regardless of the direction the particle is moving in.

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.
