If a substance cannot be separated by physical means or chemical means, it is _an element_.
Electrical force between the two charges is (attractive)
Explanation:
The magnitude of the electrostatic force between two charged particles is given by Coulomb's law:
where:
is the Coulomb's constant
are the charges of the two particles
r is the separation between the two particles
In this problem, we have:
is the charge of the first particle
is the charge of the second particle
r = 3 m is the separation between them
Substituting into the formula, we find the force:
And the negative sign means the force is attractive (the electric force between two charges with opposite sign is attractive)
