일반물리학 2 — Electric Fields: Problem 41

41 How much work is required to turn an electric dipole \( 180^\circ \) in a uniform electric field of magnitude \( E = 46.0 \text{ N/C} \) if the dipole moment has a magnitude of \( p = 3.02 \times 10^{-25} \text{ C}\cdot\text{m} \) and the initial angle is \( 23^\circ \)?
