Q.34. Find the electric dipole moment of the system shown in figure.
Dear Student ,
The charges are supposed to be fixed, they can not move. You can consider the array as if there were two -q charges at the bottom left corner, that is there are two dipoles. The dipole of the array is the resultant. A charge distribution can be characterised by its net charge and momenta. It can have a net dipole momentum, of quadrupole momentum and so on
. So it will come out to
That is the magnitude of the dipole moment. But it is a vector. Write it as a vector either with its components, or give the direction. it would be in between the two vectors at 45 degree.
