Detailed explanation-1: -Fg and Fe represents gravitational and electrostatic force respectively between electrons situated at a distance 10 cm apart. The ratio of Fg and Fe is of the order of. Q. Let the electrostatic force between two electrons (Fe) be x times the gravitational force (Fg) between them.
Detailed explanation-2: -Fe = electric force. k = a constant. q1, q2 = charges. r = distance of separation “Coulomb’s Law”. This for-mula gives the force of attrac-tion or repulsion between two charges a distance r apart.
Detailed explanation-3: -Answer and Explanation: Fe is a neutral atom and will only have London dispersion force as the dominant intermolecular force.
Detailed explanation-4: -|FE| is the magnitude of the electric force in newtons (N) k is Coulomb’s constant, equal to 8.99 x 109 newton-meters-squared-per-coulomb squared (N⋅m2/C2)
