The Bohr model of the hydrogen atom pictures the electron as a tiny particle moving in a circular orbit about a stationary proton. In the lowest-energy orbit the distance from the proton to the electron is 5.29 x 10^-11 meter, and the linear speed of the electron is 2.18 x 10^6 m/s.
a) Determine what is the angular speed of the electron?
(rad/s)
b) Determine how many orbits about the proton does it make each second?
(rev/s)
c) Determine what is the electron's centripetal acceleration?
(m/s^2)
