Answer:
The electric force between Earth and Moon cancels out because they have an equal number of positive and negative charges.
Explanation:
The electric force between any two objects is given by:
[tex]F=k\frac{q_1 q_2}{r^2}[/tex]
where
k is the Coulomb's constant
q1 and q2 are the net charges present on the two objects
r is the separation between the two objects
Due to the value of k, the electric force is generally much greater than the gravitational force (which is the weakest of the four fundamental forces). However, in this case the electric force between the Earth and the Moon is zero: this is because very large object are always neutral (they do not have a net charge, which means they have an equal amount of positive and negative charge on them). Therefore, since q1 = q2 = 0, the electric force is zero as well.
