An electric dipole is situated in a non-uniform electric field. It may experience:
Correct answer: A. A resultant force and a couple
- A. A resultant force and a couple
- B. Only force
- C. Only couple
- D. Any of the above
Explanation
An electric dipole always experiences a torque when placed in either uniform or non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So, the electric dipole in non-uniform electric field experiences both torque and force.

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.
