They repel each other.

They attract each other.

The electrostatic force decreases (inversely proportional to the square of the distance).

Electric field lines point from regions of high potential to regions of low potential.

They repel each other.

They attract each other.

The electrostatic force between them decreases (inversely proportional to the square of the distance).

The electric field strength increases.

The charge experiences a force: $$F = qE$$

A fundamental property of matter that can be positive or negative.

The law that quantifies the electrostatic force between two point charges: $$F = k frac{|q_1 q_2|}{r^2}$$

The work needed to move a charge between two points, measured in volts (V).

A region where a charge experiences a force; it's a vector field.

Electric potential is the potential energy per unit charge, a scalar quantity measured in volts (V).

A measure of the electric field passing through a given area: $$Phi_E = E cdot A = EA cos( heta)$$.

Relates the electric flux through a closed surface to the enclosed charge: $$oint E cdot dA = frac{Q_{enc}}{epsilon_0}$$.
