While the electric field caused by a dipole changes inversely with the cube of the distance, the electric field caused by an isolated point charge changes inversely with the square of the distance.
What will happen to an isolated positive charge's electric field of force?
The electric field surrounding a single positive charge is directed radially outward because positive charges resist one another. Electric fields are typically shown as lines of force or field lines, which begin on positive charges and end on negative charges.
What is an isolated system's overall charge?
According to the law of conservation of charge, the net charge of an isolated system will never change. This indicates that no system will ever have a different total charge between any two moments if it is not exchanging mass or energy with its surroundings.
