Question

Which of the following is not true?

• 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

Answer: (C)

The electric dipole potential varies as 1/r at large distance.

Answer 2

: The electric dipole potential varies as $\frac{1}{r}$at large distance is not true.
