Vedclass · Answer

(C) $1$. For $x $2$. For $x > a$,the electric field $E$ is positive. Since $E$ is directed towards the positive $x$-axis near $x=a$,$Q_2$ must be positive.$3$. The electric field becomes zero at some point $x > a$. This implies that the magnitude of the electric field due to $Q_1$ at that point must be equal to the magnitude of the electric field due to $Q_2$. Since the point where $E=0$ is closer to $Q_2$ than to $Q_1$,it follows that $|Q_1| > |Q_2|$.$4$. Therefore,$Q_1$ is negative,$Q_2$ is positive,and $|Q_1| > |Q_2|$. The correct option is $C$.

Two point charges $Q_1$ and $Q_2$ are fixed at $x = 0$ and $x = a$. Assuming that the electric field strength is positive in the direction coinciding with the positive direction of $x$,which of the following options is correct?
