Coulomb’s Law

linearly proportional

The magnitude of the force is _____________________ to the net charge on each objects

inversely proportional

The magnitude of the force is _____________________ to the distance between the objects.

mass

Electric force does not depends on the ____ of the objects.

|F| = (1/4πε0)*(|q1q2|/r²)

Formula for the magnitude of the electric force between two electrically charged particles

Repelling force is shown

Both the charges have the same sign, the force is in the same direction as r

Attracting force is shown

Charges have different signs, the force is in the opposite direction of r

Electric force

A function of the separation distance between the two charges

constant

Electric force is not a ________

ε0

Symbol that represents the permittivity of free space also called permittivity of vaccum.

8.85×10^-12 C²/N*m²

Value of ε0

k

Symbol that represents coulomb constant

k = 1/4πε0

Formula of the Coulomb’s constant

8.99×10^9 N*m²/C²

Value of the Coulomb’s constant

Principle of superposition

An important feature of the electric force. The ability to just add all electric forces together as vector.

Constant positions of the source charges.
