An electron with charge −e and mass m moves in a circular orbit of radius r around a nucleus of charge Ze, where Z is the atomic number of the nucleus. Ignore the gravitational force between the electron and the nucleus. Find an expression in terms of these quantities for the speed of the electron in this orbit. (Use any variable or symbol stated above along with the following as necessary: k for Coulomb's constant.) v = ?

The electric force is much stronger than the gravitational force
so we can often neglect gravity in electricity and magnetism. How
far does the electron of a hydrogen atom have to be removed from
the nucleus (contains only one proton) for the force of attraction
equal the weight of the electron at the surface of the Earth (g=9.8
m/s2)? Is that large compared to the size of an atom?
