NEET Physics Electric Field MCQ Question
Which of the following statements about electric fields is correct?
The electric field due to a point dipole falls off as 1/r^3 at large distances.
The direction of the electric field is always towards the source charge.
The electric field can be defined even if the test charge is not negligibly small.
Electric field strength is independent of the angle between the position vector and dipole moment.
Correct Answer
Detailed Explanation
The dipole field at large distances indeed falls off as 1/r^3, as mentioned in the context. The other statements are incorrect as the electric field direction depends on the charge type, the definition requires a negligibly small test charge, and the electric field strength does depend on the angle with respect to the dipole moment.
