An electron is held within an electric field. What happens when the electron is released?
Correct answer: D. It accelerates in the direction opposite to the electric field
- A. It moves in the direction of the electric field
- B. It accelerates in the direction of the electric field
- C. It moves in the direction opposite to the electric field
- D. It accelerates in the direction opposite to the electric field
Explanation
An electron is held within an electric field, when the electron is released it accelerates in the direction opposite to the magnetic 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.
