NEET Physics Electric Field Assertion Reason Question
Assertion (A): The electric field due to a point charge decreases with the square of the distance from the charge. | Reason (R): The number of electric field lines crossing a surface enclosing the charge remains constant, regardless of the distance from the charge.
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 point charge decreases with distance as 1/r^2, while the constancy of field lines relates to their density distribution, not directly explaining the inverse square law effect.
