In the Rutherford Model of the Hydrogen Atom, a Proton $\pi\\(\varepsilon$

question 21

Multiple Choice

In the Rutherford model of the hydrogen atom, a proton (mass M, charge Q) is the nucleus and an electron (mass m, charge q) moves around the proton in a circle of radius r. Let k denote the Coulomb force constant (1/4 $\pi\\(\varepsilon$ ₀) and G the universal gravitational constant. The ratio of the electrostatic force to the gravitational force between electron and proton is:

• A) kQq/GMmr²
• B) GQq/kMm
• C) kMm/GQq
• D) GMm/kQq
• E) kQq/GMm
