Calculate Dipole Energy





Formula

The formula to calculate the dipole energy (U) is:

\[ U = p \cdot E \cdot \cos(\theta) \]

Where:

Definitions

Example

Let's say the dipole moment (p) is 2 C·m, the electric field strength (E) is 5 N/C, and the angle (θ) is 30 degrees. Using the formula:

\[ U = 2 \cdot 5 \cdot \cos(30^\circ) \]

We get:

\[ U = 2 \cdot 5 \cdot \frac{\sqrt{3}}{2} = 5\sqrt{3} \, \text{J} \]

So, the dipole energy is approximately 8.66 J.
