According to Coulomb's Law, the amount of electric force depends on which two things?

a
the mass of each of the particles and the distance between them
b
the size of the charge on each of the two particles and the gravitational force between them
c
the size of the charge on each of the two particles and the distance between them
d
the mass of each of the particles and the gravitational force between them

c) the size of the charge on each of the two particles and the distance between them.

The correct answer is option c: the size of the charge on each of the two particles and the distance between them.

Coulomb's Law states that the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
