In the Bohr model of hydrogen atom, the electron is pictured to rotate in a circular orbit of radius `5xx 10^-11 m`, at a speed `2.2 xx 10^6` m/ s. What is the current associated with electron motion? |

Answer» Frequecncy of revolution of electron can be wirtten as, `f=(v)/(2pir)=(2.2xx10^(6))/(2pi(5xx10^(-11)))=7.1xx10^(15)Hz` `:.` Currently associated, `I=q//t=qf=(1.6xx10^(-19))(7xx10^(15))( :. (1)/(t)=f)` `=11.2xx10^(-4)A=1.12mA` |
