Help calculating linear speed of an electron?

According to the Bohr Model of the Hydrogen Atom, the elctron orbits the proton a ta radius of 5.29x10-11m.
(a) What is the linear speed of the electron?
(b) What is the angular speed of the electron?
(c) How long does it take for the electron to complete one orbit?

I know how to solve for parts b and c, but do not know how to answer a, and thus can't solve the other two parts.

For part a, I have the the net force acting upon the electron is equal to mVt2/r. What exactly is the net force on the electron? Is it Fe or Fg or both?

I calculated Fe earlier and attained a value of 0.00816 N.

I would assume the electric force of attraction between the proton and electron in hydrogen would provide the centripetal force of the electron.

Yeah, you're right. Thank you. I realized that the Fg would be negligible in this case.
