NEET Physics Electric Field Assertion Reason Question
Assertion (A): The electric field due to a dipole at a large distance on its equatorial plane is inversely proportional to the cube of the distance. | Reason (R): The electric field of a dipole at any point depends on the inverse square of the distance 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 electric field due to a dipole on its equatorial plane at a large distance is indeed inversely proportional to the cube of the distance (1/r^3), while the reason incorrectly states an inverse square (1/r^2) dependence.
