According to Bohr's theory, the time averaged magnetic field at the centre (i.e., nucleus) of a hydrogen atom due to the motion of electrons in thenthorbit is proportional to: (n=principal quantum number)

Options:

Answer:
D
Solution:

v z n

r n 2 z

B= μI 2R

I= e T = e ( 2πR v ) = e 2π v R

B= μ 0 2 e 2π v R 2

B= μ 0 e 4π z n ( n 2 z ) 2

B=μ0e4πz3n5

B n 5 .
