kg?
o a. 0.00053 kg/m3
ob. 0.0019 kg/m3
o c. 1900 kg/m3
o d. 1.9 kg/m3

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

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
