Forces acting on a negative charge are always _.
Correct answer: A. In the direction opposite to the electric field
- A. In the direction opposite to the electric field
- B. In the direction of the electric field
- C. In the direction perpendicular to the electric field
- D. In the direction perpendicular to the velocity of charge
Explanation
Assume that a positively charged plate is on the left and a negatively charged plate is on the right. Electric field lines will go from left to right. However, the force on a negative charge will be on the left towards the positive plate. So force is in the direction opposite to the electric field. Hence Option A is correct.

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.
