Halliday, Resnick & Walker — Electric Fields: Problem 21

21 An electron is released from rest on the axis of an electric dipole is 25 nm from the center of the dipole. What is the magnitude of the electron’s acceleration if the dipole moment is \(3.6 \times 10^{-29} \text{ C}\cdot\text{m}\)? Assume that 25 nm is much larger than the separation of the charged particles that form the dipole.
