In which orientation,a diole placed, in a uniform field is in (i) stable (ii) unstable equilibrioum?

Explanation

To determine the orientation of a dipole in a uniform electric field for stable and unstable equilibrium, we can analyze the potential energy of the dipole in relation to the electric field.

### Step-by-Step Solution:

1. **Understanding the Dipole in an Electric Field**:
- A dipole consists of two equal and opposite charges separated by a distance. When placed in an electric field, it experiences a torque that tends to align it with the field.

2. **Potential Energy of a Dipole**:
