The ozone molecule o3 has a permanent dipole moment of 1.8x10-30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5× 10-10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion. ▼ part a what is the frequency f of oscillation? express your answer with the appropriate units f-value units submit uest answer
