1) The electrostatic force between the two pieces of paper is
2)
- If the charges of the two pieces of paper are both + or both -, they repel each other
- If the charges of one piece of paper is positive and the other one is negative, they attract each other
Explanation:
1)
The electrostatic force between two charged objects is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, we have the following situation:
is the charge on the first piece of paper
is the charge on the second piece of paper
is their separation
Substituting into the equation, we find the magnitude of the electrostatic force between them:
2)
The electrostatic force can be either attractive of repulsive, depending on the relative sign of the charges of the objects involved.
In particular, we have:
- If the two charges have same sign (both positive or both negative), the force between them is repulsive
- If the two charges have opposite sign (one positive and one negative), the force between them is attractive
Therefore, in this case:
- If the charges of the two pieces of paper are both + or both -, they repel each other
- If the charges of one piece of paper is positive and the other one is negative, they attract each other
