Gauss's Law: Practice Problem & Solution
A dipole of dipole moment $\vec{p}$ is placed in uniform electric field $\vec{E}$ then torque acting on it is given by: (2001)
Solution Explained:
To solve this problem, we apply the core principles of Gauss's Law. Understanding the underlying formula is key to arriving at the correct answer below:
The torque acting on an electric dipole in a uniform electric field is the cross product of the dipole moment and the electric field. Thus, $\vec{\tau} = \vec{p} \times \vec{E}$.
