NEET Physics Electrostatic Potential And Capacitance Electric Potential Due To Dipole MCQs

Two equal and opposite charges $+q$ and $-q$ are separated by a small distance $2a$. A third charge $+Q$ is placed at a distance $r$ from the midpoint of the dipole along its axial line, where $r >> a$. If the dipole is rotated by $90^\circ$ about its midpoint, the potential energy of the system changes by:

An electric dipole with dipole moment $\mathbf{p} = p_0\mathbf{i}$ is placed at the origin. The electric potential at a point $(r, heta)$ is $V$. If $r >> a$, where $2a$ is the dipole separation, which of the following is correct regarding the equipotential surfaces?
