List of top Physics Questions on Electric Potential and Electric Potential Energy 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 \(\frac{1}{r}\) respectively. Here \(r\) represents the distance of the point from the two point charges.

(I) Identify the nature of the two charges \(Q_1\) and \(Q_2\).
(II) What is the value of \(\left(\frac{Q_1}{Q_2}\right)\)? Justify your answer.
