Answer :
Final answer:
In the expression for electrostatic force, the variable that would vary for different elements like carbon and nitrogen would be the Charge(A).
Explanation:
The electrostatic force between two charged particles is given by Coulomb's law, which is represented as F = k * |q1*q2|/r², where F represents the force, q1 and q2 are the charges of the particles, r is the distance between the particles, and k is Coulomb's constant that encompasses the permittivity of the medium.
The charge (q1 and q2) would vary for different elements like carbon and nitrogen, as it depends on the number of electrons or protons. Mass is not a variable in this expression. So, for carbon and nitrogen, the variable that would be different in the expression for the electrostatic force would be the Charge (A).
