Vedclass · Answer

(A) The Bohr magneton $(\mu_B)$ is a physical constant related to the magnetic moment of an electron caused by its orbital or spin angular momentum.It is defined as $\mu_B = \frac{eh}{4\pi m_e}$.Substituting the values of the elementary charge $(e)$, Planck's constant $(h)$, and electron mass $(m_e)$:$\mu_B \approx 9.274 	imes 10^{-24} \ J \cdot T^{-1}$ (or $A \cdot m^2$ since $J \cdot T^{-1} = A \cdot m^2$).Thus, the correct value is $9.27 	imes 10^{-24} \ A \cdot m^2$.

The value of $1$ Bohr magneton $(\mu_B)$ is equal to ......... $A \cdot m^2$.
