The current associated with an electron of charge e moving in a circular orbit of radius r with speed v around the positively charged nucleus is given by
Options
- Ae r 2 v
- Be 2 r v
- Ce v r
- De v 2 r
Correct answer
D. e v 2 r
Step-by-step solution
The current associated i with an electron e moving in a circular orbit of radius r with speed v around a positively charged nucleus can be written as: i= charge time period = q T = e (2 r) / v = e v 2 r
