(a) Use the astronomical data in Appendix $\mathrm{E}$ to compute the gravitational force between Sun and Earth. (b) Suppose gravity were turned off, and you wanted to replace the gravitational force with an electrostatic force of the same magnitude you computed in part (a). If the Sun had charge $+Q$ and Earth $-Q$, determine the value of $Q$.

Key Concepts

Newton's Law of Universal Gravitation

This principle states that every two masses in the universe attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. It provides the mathematical framework for calculating forces between astronomical bodies and is fundamental to understanding celestial mechanics.

Coulomb's Law

Coulomb's Law describes the electrostatic force between two point charges. It states that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. This law is essential for analyzing interactions in electric fields and for calculating the forces between charged objects.

Equating Gravitational and Electrostatic Forces

This concept involves setting the magnitude of the gravitational force, as predicted by Newton's Law, equal to the magnitude of the electrostatic force, as given by Coulomb's Law. By doing so, one can solve for variables—such as the charge required on each body—that would result in an electrostatic force identical in magnitude to the gravitational force. This approach demonstrates how physical forces from different fundamental interactions can be compared using their respective mathematical descriptions.
