In the Bohr model of the hydrogen atom, the electron moves in a circular orbit of radius

Question:

In the Bohr model of the hydrogen atom, the electron moves in a circular orbit of radius 0.529 x 10─10 m around the proton. Assuming the orbital angular momentum of the electron is equal to h/2π, calculate
(a) The orbital speed of the electron,
(b) The kinetic energy of the electron, and
(c) The angular frequency of the electron’s motion.
