sir why ther is difference between field due to dipole anf electric field

Hello Student,

Actually in dipole the field is created by 2 charges particle of opposite charge.
And there is no such difference it is proportional to 1/r^3 that’s it but that only because we use p vector(dipole moment) instead of just charge.

The dipole is pair of two equal and opposite charges so field due to it represents the vector sum of filed due to bothe the charges, but from one charge it is a single field.
