Abox that has a mass of 80 kg slides down a ramp with a 30 degree angle. the free-body diagram shows the forces acting on the box. ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth? answer choices are 0.5 m/s2 4.9 m/s2 8.5 m/s2 9.8 m/s2

The answer should be a.

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
