Answer to Question #261483 in Electricity and Magnetism for lamo

Question

find dipole and quadruple moments of a cube of side a carrying a total charge Q which is uniformly distributed for a cube centered at the origin

Answer 1

Dipole moment

Electric field (E)=$\frac{kq}{r^3}$

Potential (V)=$\frac{kQ}{r^2}$

Quaderpole moment

Electric field

$E=\frac{kq}{r^4}$

Potential

$V=\frac{kQ}{r^3}$
