Physics Bohr Model Problem?

In the Bohr model of the hydrogen atom, the speed of the electron is approximately 2.08 × 106 m/s. Find the central force acting on the electron as it revolves in a circular orbit of radius 5.45 × 10−11 m Answer in units of N Find the centripetal acceleration of the electron. Answer in units of m/s^2

F = m v^2 / r You need to look up the mass of the electron then merely substitute.


F = 9.1e-31 * 4.3264e12 / 5.45e-11 9.1*4.3264/5.45 e12+11-31 F= 7.224e-8 N 7.224 10-8 Newton.
