Deduce the expression for the torque acting on a dipole of dipole moment `vecP` in the presence of uniform electric field `vecE`.

Explanation

To deduce the expression for the torque acting on a dipole of dipole moment \(\vec{P}\) in the presence of a uniform electric field \(\vec{E}\), we can follow these steps:

### Step 1: Understanding the Dipole
A dipole consists of two equal and opposite charges, +Q and -Q, separated by a distance \(2L\). The dipole moment \(\vec{P}\) is defined as:
\[ \vec{P} = Q \cdot 2L \]
The direction of \(\vec{P}\) is from the negative charge to the positive charge.
