At what angle of electric dipole moment with uniform electric field, potential energy is maximum ?

Explanation

To determine the angle at which the potential energy of an electric dipole in a uniform electric field is maximum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Potential Energy**:
The potential energy (U) of an electric dipole moment (p) in a uniform electric field (E) is given by the formula:
\[
U = -\mathbf{p} \cdot \mathbf{E} = -pE \cos \theta
