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?

Text Solution

Verified by Experts

`l = (q)/(t) = (qV)/(2 pi R) ( because t ("distance")/("speed") = (2 pi R)/(V))`
`= (1.6 xx 10^(-19) C xx 2.2 xx 10^(s) m//s)/(2pi xx 5 xx 10^(-11) m) = 1.12 xx 10^(-3) A`
` = 1.12 mA`
