Answer:
Explanation:
electron attraction between electron and nucleus = centripetal force of the orbiting electron
In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus.
Answer:
Fg = G M m / R^2 the gravitational force (M proton, m electron)
Fe = K e^2 / R^2 the electrical force where K = 9 *10E9 and e = charge
Fe / Fg = K e^2 / (G M m)
Fe / Fg = 9 * 10E9 * (1.6 * 10E-19)^2 / (6.67 * 10E-11 * 1.67 * 10E-27 * 9.11 * 10E-31
9 * 1.6^2 / (6.67 * 1.67 * 9.11) * 10^-29 / 10^-69
= 2.27 * 10E39 for the ratio of the two forces
