307188 According to Bohr's theory, the angular momentum for an electron of \(3^{\text {rd }}\) orbit is

1 \(3 \hbar\)
2 \(1.5 \hbar\)
3 \(9 \hbar\)
4 \(2 \dfrac{\hbar}{\pi}\)

307189 An electron from one Bohr stationary orbit can go to next higher orbit

1 by emission of electromagnetic radiation.
2 by absorption of any electromagnetic radiation.
3 by absorption of electromagnetic radiation of particular frequency.
4 without emission or absorption of electromagnetic radiation.

1 Third orbit
2 Second orbit
3 Fourth orbit
4 Fifth orbit
