An electric dipole consists of two point charges $+1 \text{ }\mu\text{C}$ and $-1 \text{ }\mu\text{C}$, held $10 \text{ cm}$ apart. It is subjected to a uniform electric field of $100 \text{ N/C}$. Calculate the amount of work done in turning the dipole from its position of stable equilibrium to the position of unstable equilibrium, in the field.
