Two objects have a mass 1 $\mathrm{kg}$ and carry a charge of magnitude 1 $\mathrm{C}$ each. Which statement correctly identifies the relationship between the magnitude of the force of gravity, $\mathrm{F}_{g}$ and the magnitude of the electric force, $\mathrm{F}_{\mathrm{E}}$ , between the objects? (A) $\mathrm{F}_{\mathrm{g}}>\mathrm{F}_{\mathrm{E}}$ (B) $\mathrm{F}_{\mathrm{g}}<\mathrm{F}_{\mathrm{E}}$ (C) $\mathrm{F}_{\mathrm{g}}=\mathrm{F}_{\mathrm{E}}$ (D) Cannot be determined without knowing the sign of the charges.

Key Concepts

Newton's Law of Universal Gravitation

Newton's law of universal gravitation explains that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law is fundamental in describing gravitational interactions in classical mechanics.

Coulomb's Law

Coulomb's law describes the force between two point charges, stating that the electrical 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 forms the basis for understanding electrostatic interactions in electromagnetism.

Inverse Square Law

Both gravitational and electric forces decrease with the square of the distance separating the objects. This common mathematical dependence characterizes not only these forces but also other phenomena in physics, emphasizing the geometric nature of how intensity diminishes over space.

Comparison of Fundamental Forces

Comparing gravitational and electric forces involves recognizing that although both forces obey an inverse square law, the inherent constants (the gravitational constant versus the electric constant) are vastly different. This leads to situations where the electric force can be significantly stronger than the gravitational force under similar conditions.
