An electric dipole is situated in a non-uniform electric field. It may experience:
Correct answer: A. A resultant force and torque
- A. A resultant force and torque
- B. Only force
- C. Only torque
- D. All of these are correct
Explanation
In a non-uniform field, the forces on the two ends of the dipole will not be equal and opposite, resulting in a net force. Unless the dipole is perfectly aligned with the field, it willalso experience a net torque.

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.
