For a short electric dipole, identify the incorrect statement(s).
(A) The electric field intensity varies inversely with the cube of the distance from the center of the dipole.
(B) The electric field is directed from negative to positive charge.
(C) The electric potential at mid-point of the dipole is zero.
(D) The electric field intensity at mid-point of the dipole is zero.
Choose the correct answer from the option given below :
- A (A) and (C) only
- B (B) and (D) only
- C (A) only
- D (B) only
Answer & Solution
Correct Answer
(B) (B) and (D) only
Step-by-step Solution
Detailed explanation
Statement (B): Electric field lines originate from positive charges and terminate on negative charges. Thus, statement (B) is incorrect. Statement (D): At the mid-point of the dipole, electric fields due to \(+q\) and \(-q\) are in the same direction (from \(+q\) to \(-q\)), so…
