An average human weighs about $650 \mathrm{~N}$. If each of two average humans could carry $1.0 \mathrm{C}$ of excess charge, one positive and one negative, how far apart would they have to be for the electric attraction between them to equal their $650 \mathrm{~N}$ weight?

Key Concepts

Gravitational Force (Weight)

Gravitational force is the attractive force between masses, and an object's weight is the force exerted on it by gravity. Understanding weight as a gravitational force is crucial when comparing it to other forces, like electric forces, to determine conditions of equilibrium or balance.

Electric Force

Electric force is the interaction between charged objects resulting from their electric fields. It is quantified using Coulomb's Law and can be either attractive or repulsive depending on the signs of the interacting charges. This concept is key when comparing the electric attraction or repulsion to other forces such as gravity.

Force Equilibrium

Force equilibrium refers to a condition where the net force acting on an object or system is zero, meaning all forces balance exactly. This concept is applied when determining the separation distance required for the electric force between two charges to exactly counterbalance another force such as weight.

Coulomb's Law

Coulomb's Law describes the force between two point charges as directly proportional to the product of the charges and inversely proportional to the square of the distance between them. This law provides the fundamental basis for calculating the electrical force in systems where charged objects interact.

Electric Charge

Electric charge is a fundamental property of matter that determines how particles interact electromagnetically. It comes in two types (positive and negative), and like charges repel while opposite charges attract. Understanding charge is essential to analyzing phenomena where electrical forces are at play.
