Derive the expression for net force and torque experienced by electric dipole placed in uniform
Answers
Answer:
|p| = 2aq is placed in a uniform electric field E at an angle ϴ. A force F₁ = qE will act on positive charge and F₂ = -qE on negative charge . Since, F₁ and F₂ are equal in magnitude but opposite in direction. Thus net force on a dipole in uniform electric field is zero
Explanation:
The dipole in an electric field. Let us assume we have a uniform electric field E (constant direction and magnitude) in some region of space, and a dipole moment vector makes an angle q with the field E. The positive charge feels a force qE, So the net force on a dipole in a uniform field is zero.
When a dipole is placed in a uniform electric field and dipole vector direction is not parallel to field direction, each charge of dipole experiences a force. ... Once the dipole is aligned to electric field, the net force will be zero because they are in opposite direction.
