Vedclass · Answer

(D) $1$. By observing the electric field lines,we see that lines originate from $Q_1$ and terminate at $Q_2$. This indicates that $Q_1$ is a positive charge and $Q_2$ is a negative charge.$2$. The number of field lines originating from or terminating at a charge is proportional to the magnitude of the charge. Counting the lines,we see more lines associated with $Q_1$ than $Q_2$. Specifically,$12$ lines originate from $Q_1$,while only $6$ lines terminate at $Q_2$. Thus,$|Q_1| > |Q_2|$.$3$. For two point charges of opposite signs,the electric field is zero at a point outside the region between the charges,specifically closer to the charge with the smaller magnitude. Since $|Q_1| > |Q_2|$,the null point (where the electric field is zero) will be to the right of $Q_2$.

$A$ few electric field lines for a system of two charges $Q_1$ and $Q_2$ fixed at two different points on the $x$-axis are shown in the figure. These lines suggest that:-
