In an effort to better understand the behavior of
atomic systems, the Danish physicist Niels Bohr
(1885-1962) introduced a simple model for the
hydrogen atom. In the Bohr model, as it is known
today, the electron is imagined to move in a circular
orbit about a stationary proton. The force
responsible for the electron's circular motion is the
electric force of attraction between the electron and
the proton.
Part A
Find the orbital radius for which the kinetic energy of the electron is 2.72 eV. (Note:

In such cases, we may be able to get a good approximate solution by dividing the distribution into small but finite particles and taking the vector sum of the contributions of each.

Estimate the magnitude of the electric field at a point P a distance d = 8.0 cm from the end of the rod by dividing it into n segments of equal length as illustrated in Figure P24.21 for n = 4. Treat each segment as a particle whose distance from point P is measured from its center. Find estimates of EP for n = 1, 2, 4, and 8 segments. FIGURE P24.21arrow_forward
