Question

an electric dipole is held at an angle theta in an uniform external electric field e will there be any net translating force,torque on it,explain what happened to The Dipole on being released​

Answer 1

Answer: The dipole when released experiences no net force but experiences torque in a uniform electric field.

Explanation: No net force because both the positive and negative charges experiences equal force (qE) in the opposite directions.

There will be torque(τ) unless the dipole is perfectly aligned with the electric field. Since the dipole is aligned at an angle θ it'll experience a couple by the balanced forces and it is given vectorially by τ = p × E

and magnitude is given by τ = pEsin(θ)
