l Review Part A 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. If the speed of the electron were 4.4x105 m/s, what would be the corresponding orbital radius? Express your answer using two significant figures.
