Question

Which expression gives the quantised angular momentum of the orbiting electron?

Options

• \[L=\frac{nh}{2\pi r}\]

• \[L=\frac{h}{2\pi n}\]

• \[L=\frac{2\pi n}{h}\]

• \[L=\frac{nh}{2\pi}\]

Answer 1

The allowed angular momentum is \[L=\frac{nh}{2\pi}\]. Here \[n\] is an integer, so the allowed values are integral multiples of \[\frac{h}{2\pi}\].
