Question

here is question.


explain the charge

its si unit

and how much u can describe about it but

word limit 250 words

Answer 1

$\huge\bf{hey}$ 

$\huge{ \mathfrak{here \: is \: answer}}$

$\huge{charge}$

▶ 
$\sf{it \: is \: internal \: properties \: of \: some }$
$\sf{elementry \: particle \: for - electron }$
$\sf{proton \alpha \: particles \beta particles \: antipositron \: positron \: }$
$\sf{it \: can \: not \: be \: seen \: but \: it \: can \: be \: feel}$
$\sf{by \: experiment}$

▶ it is a scalar quantity and it is denoted by
'Q' or 'q' .

▶ the main cause of charge developed is friction so charge is also called friction electric.

▶ unit of charge

⭐ si unit - coulomb

⭐cgs or esu - stat coulomb

⭐ mks or Ems - absolute coulomb.

▶ relation between units of charge 

see in pic

▶ conservation of charge

servation theory of charge, charge is neither created nor be destroyed it is only transferred from one body to another body.

this theory age understood by the following given example

nacl

LHS 
total no of charge = 0 

rhs 

total no of charge = 1+(-1)
0

from the both example it is clear that charge is conserved

$\bf{types \: of \: charge}$

✴ positive 

✴ negative

⚫ positive charge: if any substance or element released electron then substance becomes positive charge.

⚫ negative charge : if any neutral element or substance observe or gain electron then substance becomes negatively charged.

✡ quantization theory of charge

according to quantimisation theory of charge excess charge of any body is always defined in the form of integer product of electron
q= ne

now
according to question

it is because the metal have positive charge and have free electrons and also its electrons are loosely bound with nucleus

Answer 2

Here is your answer :-


Q: Explain Charge.

Answer :- The matter consists of atom and in an atom the electrons revolves around the nucleus in elliptical orbits. The electrons in the outermost orbit of an atom are loosely bound to it and a small amount of energy is required to make them free.


S.I unit of charge : The S.I unit of charge is coulomb (C) named after Charles coulomb.
It is a scaler quantity.
Its dimensional formula is {M° L° A¹ T¹}



Properties of Charges :

1) There are two types of Charges, namely, positive and negative.

2) The magnitudes of the charge on an electron and a proton are equal, but they are unlike charges. An electron is charged negatively whereas a proton is charged positively.

3) Two charged bodies repel each other, if they contain like charges, i.e.., both positive or both negative. Two charged bodies attract each other if they contain unlike charges.

4) A neutral body becomes positively charged on losing electrons and not because of gaining protons.

5) A neutral body becomes negatively charged, when it gains electrons.



Hope it helps ;)
