Electric Dipole: Practice Problem & Solution
Assertion (A): When a dipole is placed in a non- uniform electric field dipole must experience non zero force and torque. Reason (R): Electric dipole is in stable equilibrium in non uniform electric field.
Short Solution (Best for NEET):
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:
In a non-uniform field, `\( +q \)` and `\( -q \)` experience different forces, leading to a net force and torque. Thus (A) is true. However, a dipole is generally not in stable equilibrium in a non-uniform field, so (R) is false.
