Question:

Identify the correct statements among the following.

(A) For two unlike equal charges, there is a neutral point on the middle point on the line joining the two charges.
(B) For two, unlike unequal charges, the neutral point will be outside on the line joining the two charges.
(C) For two positive equal charges, the neutral point will be at the middle point of the line joining the two charges.
(D) For two negative charges placed along a line, there will not be any neutral point.

Choose the correct answer from the options given below:

Options:

(A) and (B) only

(A) and (C) only

(B) and (C) only

(C) and (D) only

Correct Answer:

(B) and (C) only

Explanation:

The correct answer is Option (3) → (B) and (C) only

Explanation:

(A) False — For two unlike equal charges (+q and −q), the electric fields due to each are in the same direction at every point on the line joining them, so no neutral point exists between them.

(B) True — For two unlike unequal charges, the electric fields can cancel each other at some point outside the line joining them, giving a neutral point.

(C) True — For two equal positive charges, the electric fields are opposite in direction at the midpoint, hence they cancel each other and the neutral point lies at the midpoint.

(D) False — Two equal negative charges behave like equal positive charges; there is a neutral point at the midpoint.
