This selection comes from the Serway . Beichner, Physics for Scientists and Engineers text that many undergrads are (I'm sure) familiar with!(adsbygoogle = window.adsbygoogle || []).push({});

I've looked at this problem on 3 different casual occasions and on one test and still have yet to arrange the concept in my mind...

"In the Bohr modle of the hydrogen atom, an electron in the lowest energy state follows a circular path at a distance of 5.29 x 10^-11m from the proton. (a) Show that the speed of the electron is 2.19 x 10^6 m/s (b) What is the effective current associated with this orbiting electron?"

I've been considering the equation [tex] I_{av} = nqv_{d}A [/tex], which makes the answer to part (b) a gradeschool word problem. BUT, the answer probably involves implementing some equation derived four chapters ago.

Any hints would be greatly appreciated! Thanks.

John
