In the bohr model, the electron of a hydrogen atom moves in circular orbit of radis `5.3xx10^-11` m with speed of `2.2xx10^6 m//s`. Determine its frequency f and the current l in the orbit.

Text Solution

Verified by Experts

The correct Answer is:
A
`f=v/(2pir)=(2.2xx10^6)/((2pi)(5.3xx10^-11))`
`=6.6xx10^15Hz`
`I=qf`
`=(1.6xx10^-19)(6.6xx10^15)`
`=1.06 xx 10^-3A`
`=1.06mA`
