Question 19 • Physics
In Coulomb’s law, the electrical-force constant is about 8.99 × 10⁹, while the gravitational constant is about 6.67 × 10⁻¹¹. The electrical constant is vastly larger, so for the same charges and masses, it makes the electrical force much larger than the gravitational force. Therefore, the best choice is that 10⁹ is much greater than 10⁻¹¹.
