In the bohr model of the hydrogen atom, an electron moves in a circular path around a proton. the speed of the electron is approximately 2.20 x 10^6 m/s. find (a) the force acting on the electron as it revolves in a circular orbit of radius 0.530 x 10^-10 m and (b) the centripetal acceleration of the electron.

a) fc = mv^2/ r
fc = 9.1093818810^-31 * (2.210^6)^2 / (0.5310^-10)
fc = 8.3188 10^-8 n

b) ac = fc / m =
8.3187610^-8 / (9.1093818810^-31) = 9.132110^22 m/s^2
