NEET Physics Electric Field MCQ Question
Which of the following statements about electric fields is correct?
The electric field inside a uniformly charged thin shell is zero at all points.
The electric field due to a point charge decreases as 1/r.
Electric fields have no independent dynamics and are merely mathematical constructs.
An electric dipole produces a field that falls off as 1/r.
Correct Answer
Detailed Explanation
According to Gauss's law, the electric field inside a uniformly charged thin shell is indeed zero at all points, as the net enclosed charge is zero. This contradicts option B, which incorrectly states the decrease rate for point charges, and option C, which misrepresents the nature of electric fields as physical entities. Option D is also incorrect as the field of an electric dipole falls off faster than 1/r.
