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. Choose the correct answer from the options given below: |
(A) and (B) only (A) and (C) only (B) and (C) only (C) and (D) only |
(B) and (C) only |
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. |
