List of top Physics Questions on Electrostatics asked in JEE Advanced

Consider an electric dipole comprising two charges \(+q\) and \(-q\), each with mass \(m\), separated by a fixed distance \(d\) and initially at rest with its dipole moment pointing along \(\hat{i}\). A uniform electric field \(E\hat{j}\) is turned on at time \(t=0\) and it is turned off at \(t=t_f\), when the dipole moment makes an angle \(\theta_f\) with \(\hat{i}\). Neglecting any sources of energy loss, correct option(s) is/are:
Two charges $Q_1 = q$ and $Q_2 = mq$ are placed at the points $P_1(a, b)$ and $P_2(ma, mb)$, respectively, in the $XY$ plane, where $a, b \neq 0$ and $m \neq 0, 1$. If $V_1$ is the potential at a point in the $XY$ plane due to charge $Q_1$ and $V_2$ is the potential at that point due to charge $Q_2$. Correct statement(s) for the points at which $|V_1| = |V_2|$ is/are:
