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: 1 eV = 1 electron - volt 1.6 × 10-¹⁹ J.) VE ΑΣΦ r = Submit - Request Answer Ć = ? m
A E The picture shows the field lines of a nonuniform electric field and five points A to E in the field. Consider the following statements. Which one is true? This electric field may be due to a negatively charged object located to the left. A positive point charge placed at point C will feel a stronger electric force than at point D. OThe electric field strengths at points B and C are the same because they are on the same field line. OThe electric field strengths at points A and D are both zero because there are no electric field lines on them. A negative point charge placed at point C will feel an electric force pointing to the right.
