Consider the Earth and the Moon as a two-particle system. A. Find an expression for the gravitational field g vector of this two-particle system as a function of the distance r from the center of the Earth.
B. G Plot the scalar component of g vector as a function of distance from the center of the Earth.

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
