question 29

Essay

Using data from Table 3.3, calculate the ratio between the electrostatic force and the gravitational force between the proton and the electron in a hydrogen atom, if the distance between the electron and the proton is r = 5.3 × 10⁹ m. The universal gravitational constant G = 6.67 × 10^-11 m³ kg^-1 s^-2, and Coulomb's constant k = 9.0 × 10⁹ N m²/C².
