magnitude of the "current" flowing around the nucleus in the Bohr mode 1. The problem statement, all variables and given/known data According to the Bohr model, a hydrogen atom in its lowest energy state has a nucleus consisting of a single proton, which is orbited by a single electron. The speed of the electron is 2.19×106 m/s and the radius of its orbit (the "Bohr radiuis") is 5.29×10−11 m. What is the magnitude of the "current" flowing around the nucleus in the Bohr model? radius=5.29e-11 v=2.19e6 2. Relevant equations equation used : I=nAvq ( i was surfing internet and found this equation, i couldn't find equation from the book) 2nd try: equation : I = e*w, where e is elementary charge and w is revs/s. 3rd try: J=I/A J is magnitude of current density. 3. The attempt at a solution 1st: I= 1*2pi(5.29e-11)^2(2.19e6)(-1.6e-19) I= -6.16e-30 A seems very wrong. 2nd; e = 1.6022E-19 w = v/(2pi*r) I = 9.46518E-4 A ( i found this on yahoo answers, but it wasn't right, and i never seen that equation before.) 3rd: I don't know how to find the current if i use this equation. Please help.
