E)None of these is correct.

Question

Quizplus · Accepted Answer

In the Bohr model of the atom, electrons are assumed to be in stable orbits around the nucleus, and they do not radiate energy in these orbits. This is because the energy of the electron in these orbits is quantized and cannot be lost through radiation. Choices A, C, and D are all incorrect as gravitational forces are negligible at the atomic scale, the electrons do not spiral into the nucleus, and the expression given in choice D is not a valid formula in the Bohr model.
