Question

In a hydrogen atom angular momentum of an electron is 2ћ. It is measured with an accuracy of 90%. show that its angular position can not be specified

Answer 1

Answer:

For example in a hydrogen atom, the electronis orbitting the nucleus which implies theelectron should have some angular momentum, but we say in the ground state (n=1) the angular momentum (l) is zero

Answer 2

Answer:

$\sqrt{l(l + 1)} ћ = 2ћ$

${l}^{2} + l - 4 = 0$

l=1.5

So its angular position can not be specified

Hence proved.
