An electric dipole is situated in a non-uniform electric field. It may experience:
Correct answer: D. All of these options can be correct
- A. A resultant force and torque
- B. Only force
- C. Only torque
- D. All of these options can be correct
Explanation
An electric dipole in a non-uniform electric field can experience various combinations of forces and torques. The correct answer is that all scenarios are possible (Option D). The dipole can experience a resultant force and torque, only a force, or only a torque, based on its orientation and position. Option A is correct in describing a scenario with both force and torque, Option B is correct in special cases where the dipole has no torque due to its alignment, and Option C is valid when forces result in rotation without linear movement. However, Option D encompasses all possibilities, making it the most comprehensive answer.

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.
