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.)
