What is ratio of Bohr magneton to the nuclear magneton?

Options

A. `m_(1)//m_(e)`
B. `m_(p)^(2)//m_(e)^(2)`
C. 1
D. `(m_(e))/(m_(p))`

Answer

A

Explanation

Magnetic moment associated with electrons orbitting around the nucleus is given in terms of Bohr magneton `(mu_(0))`
`mu_(B)=(eh)/(2m_(e))`
e = electronic charge `m_(e)`= electronic mass, In nuclear physics, magnetic moments associated with the spins of protons and neutrons are expresssed in nuclear magnetic moments associated with the spins of protons and neutrons are expressed in nuclear magnetons `(mu_(N))`
`mu_(N)=(eh)/(2m_(p))`
`m_(p)` = mass of a proton.
`rArr" "(mu_(R))/(mu_(N))=(m_(p))/(m_(e))`
