### #5. Which of the following particles won't be deflected by an electromagnetic field

1. phosphorescence
2. Graviton ( None of the Above)
3.  Instantaneously
4. Fluoroscence
5. Gluon

## Physics Quiz Explanation:

Explanation:
Well you can see this phenomenon in your everyday
life. It’s present in the dark toys or clock dials that
tend to glow when the room or surrounding
becomes totally dark, but it’s the phenomenon that
occurs when you charge them with really bright
lights. That’s called phosphorescence i.e. emission of
light of one color from a body after it is exposed
to another color of light.
2. Which is hypothesized to be mediating
gravitational interaction?
Explanation:
The answer isn’t present in the options. Option A
Photon is the particle that mediates electromagnetic
interaction. Neutrino and Higgs boson don’t
mediate any interaction. It’s Graviton that is
hypothesized to be mediating the gravitational
interaction. It’s not sure yet. The particle must be
traveling with the speed of light.
Explanation:
In the photoelectric effect, electrons are emitted at the
instant energy or photon is incident on the
photoelectric surface. Photons transfer their kinetic
energy to electrons on the surface and
instantaneously electrons get out of the surface.
Explanation:
It’s a property of a body by which the body absorbs
light of short wavelength and emits light of longer
wavelength.
5. Which particle won’t be deflected by an
electromagnetic field?
Explanation:
The first option is Gluon which has a charge of 0. So it
won’t be deflected by the electromagnetic field. Now
we just can’t choose option A. So, go to the next option which says “All of
the above”. So next is Muon. It has an Electric charge −1 e. W Boson has
charge ±1 e. So both will be deflected by
the electromagnetic field. So the answer is Gluon.
