AIIMS 2019 Physics Electric Dipole Assertion Reason Question
On distributing an electric dipole in stable equilibrium in an electric field, it returns back to its stable equilibrium orientation. The restoring torque brings it back to its stable equilibrium. Thus, both assertion and reason are true and reason is the correct explanation of the assertion.
Both assertion and reason are true and reason is the correct explanation of assertion.
Both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion is true but reason is false.
Assertion is false but reason is true.
Correct Answer
Detailed Explanation
Option B is correct because both the assertion and the reason are true: an electric dipole in a uniform electric field does indeed experience a torque that tends to align it with the field, and this torque acts as a restoring force that brings the dipole back to its stable equilibrium orientation. However, the reason provided does not explain the assertion fully, as it does not address the specific conditions under which the dipole achieves stable equilibrium, such as the nature of the electric field and the dipole moment.
Option A is incorrect because, while both statements are true, the reason does not adequately explain the assertion. Options C and D are incorrect because both the assertion and the reason are true, ruling out any possibility of one being false.
