# Problem: The graph shows the potential energy of an electric dipole. Consider a dipole that oscillates between ±60°What is the dipole's mechanical energy?

###### FREE Expert Solution

The potential energy of a dipole oscillating in an electric field is:

where p is the magnitude of the dipole moment, E is the field strength, and θ is the angle between the dipole moment and electric field vectors.

Total energy:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{K}}{\mathbf{E}}{\mathbf{+}}{\mathbf{U}}}$

At 0°, the potential energy of the system is -2 μJ:
