Which of these stands false for Bohr's Theory?
1
An electron does not radiate energy if it stays in one orbit
2
When an electron moves from one orbit to another it either radiates or absorbs energy
3
For an electron to remain in its orbit, electrostatic attraction between electron and the nucleus which tends to pull the electron towards the nucleus must be equal to the gravitational force
4
The energy of an electron in orbit i.e. its angular momentum, MVR must be equal to a whole number n of quanta
