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 $|A|>|B|$
