Two large parallel conducting plates carrying opposite charges of equal magnitude are separated by 2.20 )if the surface charge density for each plate has magnitude 47.0 nc/m2, what is the magnitude of e_field in the region between the plates? (b)what is the potential difference between the two plates? (c)if the separation between the plates is doubled while the surface charge density is kept constant at the value in part (a), what happens to the magnitude of the electric field? (d)if the separation between the plates is doubled while the surface charge density is kept constant at the value in part (a), what happens to the potential difference?

(a) 5310.7 V/m

The magnitude of the electric field between two parallel plates is given by

where

is the surface charge density

is the vacuum permittivity

In this problem,

So the electric field here is

(b) 116.8 V

The potential difference between the two plates is given by

where

E is the magnitude of the electric field

d is the separation between the plates

Here we have

E = 5310.7 V/m

d = 2.20 cm = 0.022 m

So the potential difference is

(c) The electric field does not change

Explanation:

As stated in part (a), the magnitude of the electric field is given by

where

is the surface charge density

is the vacuum permittivity

as we can see, the value of E depends only on the surface charge density, which is kept constant in this case, so the value of the electric field strength does not change.

(d) The potential difference doubles (233.6 V)

In this situation, the separation between the plates is doubled, so:

d' = 2 d

The potential difference depends linearly on the separation between the plates:

V = Ed

where

E is the magnitude of the electric field (which is kept constant)

d is the separation between the plates

So the new potential difference will be

which means that the potential difference will double:

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

hèllo, sorry i really need some more points so if you need this qustion answered than retype it
