What is work done on dipole to rotate it form stable equilibrium position `(theta_(1) = 0^(@))` to unstable equilibrium `(theta_(2) = 180^(@))` ?

Explanation

To find the work done on a magnetic dipole when it is rotated from a stable equilibrium position (θ₁ = 0°) to an unstable equilibrium position (θ₂ = 180°), we can use the formula for work done on a magnetic dipole in a magnetic field:

### Step-by-Step Solution:

1. **Understand the Equilibrium Positions**:
- The stable equilibrium position is when the dipole is aligned with the magnetic field (θ₁ = 0°).
- The unstable equilibrium position is when the dipole is aligned opposite to the magnetic field (θ₂ = 180°).
