List of top Physics Questions on Potential Due to a Charged Particle asked in CBSE Class XII

In the figure, OA and OB show the variation of electric potential V at a point due to two point charges $Q_1$ and $Q_2$ with $1/r$ respectively. Here r represents the distance of the point from the two point charges. Identify the nature of the two charges $Q_1$ and $Q_2$.

In the figure, OA and OB show the variation of electric potential V at a point due to two point charges $Q_1$ and $Q_2$ with $1/r$ respectively. Here r represents the distance of the point from the two point charges. What is the value of $Q_1/Q_2$? Justify your answer.
