List of top Physics Questions on Electric Dipole asked in JEE Advanced

A small electric dipole $\bar{P_0}$, having a moment of inertia I about its center, is kept at a distance r from the center of a spherical shell of radius R. The surface charge density $\sigma$is uniformly distributed on the spherical shell. The dipole is initially oriented at a small angle 𝜃 as shown in the figure. While staying at a distance r, the dipole is free to rotate about its center.If released from rest, then which of the following statement(s) is(are) correct?
