An electric dipole having dipole moment P = q 2 is placed in a uniform electric field ' E '. The dipole moment is along the direction of the field. The force acting on it and its potential energy are respectively
Options
- AqE and minimum
- BqE and maximum
- C2 qE and minimum
- Dzero and minimum
Correct answer
D. zero and minimum
Step-by-step solution
A dipole has two equal and opposite charges. In a uniform electric field, the two charges will experience equal and opposite force, hence net force will be zero. The potential energy of an electric dipole is minimum in its stable equilibrium position ( =0^ )
