Question:

Which of the following statements are correct?

(A) the mid-point between the two similar and equal point charges located nearby, is called neutral point.
(B) There are maximum number of field lines at the neutral point.
(C) The work done to bring any positive charge from infinity to a point in an electric field is called the electric potential at that point.
(D) The work done to move a charge from one point to another point on the equipotential surface will be zero.

Choose the correct answer from the options given below:

Options:

(A) and (D) only

(A), (B) and (C) only

(B) and (C) only

(C) and (D) only

Correct Answer:

(A) and (D) only

Explanation:

The correct answer is Option (1) → (A) and (D) only

(A) Correct — the midpoint between two equal and like charges is often referred to as a neutral point in the sense of equipotential (though the field is not zero, the potential can be defined consistently).

(B) Incorrect — at the neutral point the field is zero, so field lines do not converge there.

(C) Incorrect — electric potential is the work done per unit charge in bringing a test charge from infinity, not simply the work done itself.

(D) Correct — on an equipotential surface the potential difference is zero, hence no work is required to move a charge.

Answer: (A) and (D)
