NEET Physics Electric Field Assertion Reason Question
Assertion (A): The electric field due to a dipole at large distances falls off as 1/r^3.
Reason (R): The magnitude and direction of the dipole field depend only on the distance r from the dipole.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true as the dipole field decreases with 1/r^3 at large distances. However, the reason is false because the dipole field depends on both the distance r and the angle between the position vector and the dipole moment.
