Question

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

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

Answer 1

The correct option is A $A$ is $+$ve and $B$ $-$ve, $\left|A\right|>\left|B\right|$

Since lines of force starts from $A$ and ends at $B$, so $A$ is $+$ve and $B$ is $-$ve. Lines of forces are more crowded near $A$, so $A>B$
