At what angle between dipole moment and electric field, electric dipole remains in stable equilibrium in uniform electric field ?

Explanation

To determine the angle at which an electric dipole remains in stable equilibrium in a uniform electric field, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Dipole and Electric Field**:
An electric dipole consists of two equal and opposite charges separated by a distance. The dipole moment \( \vec{P} \) is a vector quantity pointing from the negative charge to the positive charge. The electric field \( \vec{E} \) is a vector that influences the dipole.

2. **Torque on the Dipole**:
