• A. For a point charge, electrostatic potential varies as $1/r$
• B. For a dipole, the potential depends on the magnitude of position vector and dipole moment vector
• C. The electric dipole potential varies as $1/r$ at large distance
• D. For a point charge, the electrostatic field varies as $1/r^{2}$.

Answer 1
