The document is a student submission that contains responses to questions about electron behavior. It discusses: 1) Centrifugal force arises from an electron moving in a circular path, and acts outwardly away from the center of rotation. The electron experiences centrifugal force from the middle point of its circular orbit. 2) Electrons rotate in orbits around the nucleus due to forces. They cannot change energy levels or escape the orbit without external interaction. Their behavior is probabilistic rather than classical circular motion. 3) According to Bohr's model, electrons travel in circular paths or orbits around the nucleus. They cannot escape the cyclic path due to forces acting on them and can only be found at certain distances from the

2. Where does electrongets Centrifugal force?
Centrifugal force is a fictitious force peculiar to a particle moving on a
circular path, that has the same magnitude and dimensions as the force
that keeps the particle on its circular path (the centripetal force)but points
in the opposite direction.Centrifugalforceisused to refer to an initial force
that appearsto act on all object. When viewed in a rotating reference, drawing
them away from the axis.
Generally Centrifugal force felt by an electron moving in a curved path that
acts outwardly away from the center of the rotation.electron get centrifugal
force from the middle point of its circular path.
Why electron rotate in an orbit?
We cannot change the energy of the electron, hypothetically or really,
exceptby the allowed transitions from one energy level to another. That is
what quantization means in the microcosm.There is no energy incoming or
outgoing in the sysem "nucleus-electron" unless there is external
interaction. That is the whole point of quantum mechanics. We only know

3. what the electronis doing if we interact with it. Otherwise we only have
probability distributions of where it may be if we interact with it. It is not
rotating in the sense of classical physics, like the moon around the
earth.Electrons are negatively charged.Electroncan not go out orbit for
force.
Rather there is a certain probability to find it certain position and distance from
the nucleus.Electrons arerotate in orbit.For forceelectrons are rotate in an orbit.
Why electron travel in a cycle?
In Bohr’s model of the the electron is visualized as revolving around the nucleus in
a circular path. Itimplies that if a suitable experiment were performed, the
electron would always be found a distance of r n2a0 (wheren is the quantum
number of the orbit and a0 is the radius of the innermostorbit) fromthe nucleus
and in the equatoria, while its azimuth angle.For velocity electron travel in cycle.

4. fromthe “Bohr Model” we know that electron travel in a circular path and cycle.
We cannot even think of the electron as moving around the nucleus in any
conventional sensesince the probability density is independent of time and
varies fromplace to place.
Electron can not go out fromthe cycle for force ,so electron travel in cycle.
