Question

The spatial distribution of the electric field due to two charges $(A $ and $B)$ is shown in figure. Which one of the following statements is correct?

• A. $A$ is $+ ve$ and $B$ is $-$ ve and $| A |>| B |$
• B. $A$ is $- ve$ and $B$ is $+ ve$ and $| A |=| B |$
• C. Both are $+ve$ but $A > B$
• D. Both are $-ve$ but $A > B$

Answer 1

Answer: (A)

The lines proceed from the positive charge and will reach $B$, if $B$ is negative.
The number of lines / unit area, i.e., the density of lines is greater for the greater charge.
$A$ is $+$ ve, $B$ is $-ve$ and $|A|>|B|$
