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

The correct Answer is:
A, B
`i=qf=q(v/(2piR))`
`=((1.6xx10^-19)(2.2xx10^6))/((2pi)(5xx10^11))`
`=1.12xx10^-3A=1.12mA`
