Electric Dipole: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Electric Dipole. Understanding the underlying formula is key to arriving at the correct answer below:

For an isolated system of two dipoles, the torques they exert on each other are internal forces. Internal torques within a system cancel each other out, leading to zero net torque on the system. Therefore, according to the conservation of angular momentum                            \(\frac{d\vec{L}}{dt} = \vec{\tau}_{ext}\)), if the net external torque is zero, the angular momentum of the system is conserved. Hence, both assertion (A) and reason (R) are false.
